Axel Brandenburg Nordita Professor, Deputy Director

Professor Axel Brandenburg received his PhD at the University of Helsinki in 1990. After two postdocs at Nordita in Copenhagen and at the High Altitude Observatory at the National Center for Atmospheric Research in Boulder/Colorado he returned to Nordita as Assistant Professor for just over a year before he went in 1996 as full Professor of Applied Mathematics to the University of Newcastle upon Tyne. In 2000 he moved once again to Nordita, this time as full professor. He became professor at the Department of Astronomy in Stockholm when Nordita moved from Denmark to Sweden in 2007

Axel Brandenburg is working in the field of astrophysical fluid dynamics and has also an interest in selected topics of astrobiology. He is particularly interested in the question of magnetic field generation from turbulent motions with applications to the Sun and stars, accretion discs, galaxies, and the early Universe.

His work on accretion disc turbulence was the first to show that the magneto-rotational and dynamo instabilities lead to a sustained doubly-positive feedback. Recently, he contributed to clarifying the long-standing question of the suppression of the dynamo effect in generating large-scale fields. He is also responsible for the maintenance of the Pencil Code, which is a public domain code ( for astrophysical fluid dynamics that is well suited for large clusters with distributed memory.

In 2009 he received funding from the European Research Council for a project on Astrophysical Dynamos with a volume of 2.22 M € to support 4 PhD students, 4 post-docs, one assistant professor and several senior visitors.

Paolo Di Vecchia Nordita professor emeritus

Paolo Di Vecchia received his degree (Italian Laurea) at the University of Rome in 1966. After a post-doctoral fellowship at the Laboratori Nazionali di Frascati he was offered a permanent position there. After two-year positions at MIT and CERN he became Assistant Professor at Nordita, 1974-1978. After another year at CERN he became Professor first at the Freie Universität in Berlin in 1979 and then at the University of Wuppertal, 1980 to 1986. He came to Nordita in February 1986.

Paolo has worked and continues to work on the theory of elementary particles by using perturbative and non-perturbative methods both in field and string theories. His recent work has dealt with the extension of the AdS/CFT correspondence to less supersymmetric and non-conformal gauge theories deriving many properties of these theories, as the beta-function and the gaugino condensate of N=1 super Yang-Mills, from the supergravity solution. Another activity has been the construction of the four-dimensional low-energy Lagrangian from toroidal compactifications in magnetized D branes models that have the important property of generating chiral matter necessary for describing quarks and leptons. In this framework, he has computed the moduli dependence of the Kaehler metrics and of the Yukawa couplings using both stringy instantons and field theoretical methods. Most recently, he has studied high-energy scattering of closed strings on a stack of D branes in various regimes of impact parameter and 't Hooft coupling.

Since 1994, he has coordinated the organization of Nordic meetings in string theory bringing together Nordic researchers and students twice a year to learn about recent developments in the field. He has organized summer schools in field and string theory for Nordic students and supervised Nordic students. He was elected in 2003 member of the Det Kongelige Norske Videnskabers Selskab.

Ralf Eichhorn Nordita assistant professor

Ralf Eichhorn received his PhD from the University of Augsburg in 2000. After postdoctorial work in Augsburg and Bielefeld, he joined Nordita in January 2009. His general research interest is on the statistical mechanics of complex systems with application to biophysical problems.

Ralf's current research activities are centered around the theory of transport processes in non-equilibrium systems, where thermal noise typically plays a dominant role. Apart from studying idealized stochastic models, Ralf is also interested in developing concrete realizations of such transport phenomena, aiming at biophysical applications in microfluidic devices (lab-on-a-chip) for the separation, purification or mixing of colloidal particles and complex biomolecules like DNA or proteins. This is motivated by the vision of a lab-on-a-chip, which combines all preparational and analytical steps of a diagnostic device in a single microfluidic system. A further direction in Ralf's research covers the dynamic aspects of molecular recognition. Molecular recognition of two biomolecules occurs due to (non-specific) interactions between complementary regions on their surfaces. Within the framework of coarse-grained models for the molecules, the dynamic aspects of the recognition process in the crowded environment of a cell are studied. More recently, Ralf became interested in stochastic thermodynamics, a new field in non-equilibrium statistical mechanics addressing the problem of generalizing and extending concepts from equilibrium statistical physics to the non-equilibrium realm.

Ralf has intense collaborations with scientists at KTH and has established contacts to several groups in the Nordic countries (e.g., Aarhus, Lund, Gothenburg). He organized two "Nordic Workshops on Statistical Physics" (March 2010 and Feb 2011), is co-organizer of a workshop on DNA self-assembly (May 2011) and of two four-week scientific programs at Nordita (fall 2011 and spring 2012). Moreover, Ralf co-organizes an international seminar series on "Complex systems and biological physics".

Matthias Geilhufe Nordita postdoc

Matthias Geilhufe got his Ph.D from Martin Luther University Halle-Wittenberg (Germany) in December 2015. As a PhD student he was employed at the Max Planck Institute of Microstructure Physics in Halle (Saale).

Matthias' research is based on the development and application of methods for the theoretical investigation of materials. In the focus are approaches based on density functional theory or group theory. He is mainly interested in magnetic properties of materials and in describing materials with a Dirac-like dispersion relation for the quasiparticles near the Fermi surface.

In the future Matthias will apply modern approaches, e.g. based on data mining or machine learning to characterize and predict Dirac materials.

Monica Guică Assistant Professor, Nordita Corresponding Fellow

Monica Guică obtained her PhD from Harvard in 2008, followed by a postdoc in Paris LPTHE and CEA Saclay, and one at UPenn.

Monica's research is centered around understanding gravity at a fundamental level. Important clues from black hole physics show that gravity is holographic, i.e. that a gravitational theory on a given space-time can be described by a field theory in lower dimensions. Her interests are focused on finding the microscopic description of black holes - especially realistic ones - using holography, on understanding the holographic dictionaries in instances that go beyond the well-studied AdS/CFT correspondence, and on understanding the emergence of space-time and gravity from the dual field theory perspective, using entanglement. While holography and the mechanism of emergence of space-time are believed to be universal, string theory, as the only consistent theory of quantum gravity known to date, provides an invaluable concrete framework for studying these questions.

John Hertz Nordita professor emeritus

John Hertz received his PhD from the University of Pennsylvania in 1970. After a postdoc at the Cavendish Laboratory, University of Cambridge, he joined the faculty of the James Franck Institute, University of Chicago as an Assistant Professor. He became Professor at Nordita in Copenhagen in 1980. Since 2007 he has also been Professor at the Niels Bohr Institute and, since 2014, visiting Professor in the Department of Neuroscience, Faculty of Health Sciences at Copenhagen University. He divides his time between Copenhagen and Stockholm.

In the beginning of his career, John worked in condensed matter theory, particularly on magnetism in systems with highly correlated electrons and on phase transitions, which led to his well-known work on quantum critical phenomena. He then turned to the statistical mechanics of disordered systems, particularly spin glasses. This, in turn, led him to develop an interest in neural networks. With Anders Krogh and Richard Palmer, he wrote what is still the standard book on artificial networks. In recent years he focused on biological networks, particularly on modeling the dynamics of neural networks in the neocortex and the problem of inferring connectivity (and other network features) from recorded neuronal spike trains. His current work deals with stochastic properties of protein and gene networks in cells.

His collaborative activity in the Nordic region includes organizing two Nordic networks on neural computation, teaching and collaboration with groups in Norway and Sweden, numerous summer schools and conferences, and supervision of MS and PhD students.

Sabine Hossenfelder Assistant Professor, Nordita Corresponding Fellow

Sabine Hossenfelder received her PhD from the University of Frankfurt, Germany, in 2003. She worked as a postdoc at the University of Arizona, Tucson, and later at the University of California, Santa Barbara, and the Perimeter Institute in Waterloo, Canada. Sabine joined Nordita in September 2009.

Sabine's main research interest is physics beyond the standard model, with a special emphasis on the phenomenology of quantum gravity. This still young research field brings together experimentalists and theorists and connects many different areas, from cosmology and astrophysics over neutrino physics to particle colliders and high precision measurements. Her contributions are focused on the role of Lorentz-invariance and locality, which might be altered in the fundamental to-be-found theory of quantum gravity and be accessible to experiment.

Sabine has collaborators at Perimeter Institute in Canada, at the University of Sussex, at SISSA in Trieste, and the MPI in Potsdam, Germany. At Nordita, she has organized a workshop on "Experimental Search for Quantum Gravity" in summer 2010 that was well attended by Nordic and international participants.

Alexander Krikun Nordita assistant professor

Alexander Krikun eceived his PhD in theoretical physics in 2011 in the Institute for Theoretical and Experimental Physics (ITEP), Moscow, Russia. He was a Nordita Fellow in 2013-2015 and then a PostDoc in Leiden University in 2015-2019. Now he rejoined Nordita as an Assistant Professor, supported by the VR Starting Grant, call 2018.

Alexander's main subject of interest is the development of Holographic Phenomenology for Quantum Matter, based on the concept of AdS/CFT duality, originating from String Theory. This theoretical tool allows one to address the behavior of strongly entangled quantum systems by means of a General Relativity model in auxiliary curved spacetime. The resulting unusual phenomenology can be directly compared to the data obtained in Condensed Matter Experiments.

Juri Poutanen Professor, Nordita Corresponding Fellow

Juri Poutanen got his PhD from the University of Helsinki in 1994. After that he was a postdoc at Stockholm Observatory for two years, and assistant professor at Uppsala University and then at Stockholm University. In 2001, he moved to the full professor position at the University of Oulu in Northern Finland. He was elected member of the Finnish Society of Sciences and Letters in 2009. From 2014, he is professor at University of Turku and director of Tuorla observatory.

Juri Poutanen works on various aspects of high-energy astrophysics. His research interests include gamma-ray bursts and accreting compact objects such as black holes, neutron stars and white dwarfs. His main expertise is radiative processes in relativistic plasmas that shape the spectra and are responsible for the emission from these objects. His most influential papers concern detailed study of Compton scattering including polarization properties that are again in the focus of many proposed space X-ray polarimetry missions. Other important results concern super-Eddington accretion disks around black holes which are relevant for ultra-luminous X-ray sources, emission mechanisms of relativistic jets in active galaxies and gamma-ray bursts, understanding broad-band emission of accreting black holes, and determination of neutron star parameters from the pulse profiles of accreting millisecond pulsars. Recently he concentrated on studying accretion onto strongly magnetized neutron stars and understanding the nature of ultra-luminous X-ray pulsars. He is also actively involved in development of atmosphere models for hot neutron stars and their usage to determine neutron star parameters in order to constrain the equation of state of cold dense matter.

Alexandra Veledina Nordic assistant professor

Alexandra Veledina got her PhD from the University of Oulu, Finland, in 2014. She made a short postdoc at the University of Turku before moving to Stockholm as Nordita fellow in 2016. Since September 2017, she is Nordic assistant professor on a joint appointment with the University of Turku, Finland.

Her research is in the field of radiative processes in nearly-Maxwellian relativistic plasmas. In particular, her works are concentrated on modeling spectral and temporal characteristics of accreting compact objects such as black holes and neutron stars. She developed an accretion flow model capable of explaining many enigmatic multiwavelength observations obtained recently: correlated fast optical and X-ray variability, quasi-periodic oscillations and strong non-thermal infrared/optical flares. Her works raised attention to the importance of combining spectral and timing techniques.

Alexandra continues to work with astrophysical accretion flows, now paying more attention to the flow microphysics, rather than the observed characteristics. She plans to develop an MHD code capable of describing dynamics of accretion flow with non-Maxwellian electrons, relevant to black hole accretion environment.

Dmytro Volin Nordic assistant professor

Dmytro Volin received his PhD from the Université Paris-Sud XI in September 2009. His thesis was conducted and supervised at the Institut de Physique Théorique, Saclay. From October 2009 till October 2011 he had a postdoctoral position at the Pennsylvania State Univeristy, then he moved to Sweden to join Nordita for his second postdoc.

Dmytro's main interests are strongly interacting field theories and integrable systems, with emphasis on the integrability in AdS/CFT. In his works, he contributed to the solution of the AdS/CFT spectral problem, in particular to the solution of crossing equations and to a pioneer derivation of an AdS/CFT analog of Destri-de Vega equations. At present he is working on the bootstrap program for integrable systems at finite volume. This is in line with one of his long-term goals: to understand microscopic mechanisms behind the AdS/CFT duality, in N=4 SYM and beyond, without direct appeal to string theory.

Currently he has several active collaborations with scientists from France, Belgium, UK and USA. Dmytro is teaching an advanced online course on quantum integrability.

John Wettlaufer Nordita professor

John S. Wettlaufer is the A.M. Bateman Professor of Geophysics, Physics and Applied Mathematics at Yale University. His training is in the statistical physics of phase transitions but over the years it has branched out substantially across many disciplines in soft condensed matter physics and applied mathematics with impinging upon biophysics, geophysics and most recently, due to his time here previously, astrophysics.

His stay at Nordita in the fall of 2011 is supported by the Wenner-Gren Foundation, and he has been awarded the Tage Erlander Guest Professorship for 2012. The holder of this chair is appointed by invitation from the Swedish Research Council.

John will be working on the stochastic dynamics generally with applications to abrupt changes in Arctic climate and in fluid dynamics generally. In the former case, the basic problem is one of predicting the future using imperfect and highly variable global climate computer models versus the questionable activity of extrapolating to the future using a 31 year time series of high resolution satellite data. This leaves a spate of possibilities for "simple" mathematical models, rigorous studies of the origin and nature of variability and periodicity, and a focus on the multiplicity of time scales embedded in the data, examined in the context of the singularity spectrum of multifractals. These approaches have an origin in the statistical mechanics of fluctuating systems with major insights originating in stochastic and numerical models of turbulence, dynamos and a wide variety of other systems. He hopes also to begin the process of incorporating the microphysical conditions for planetary accretion studied during his previous visit into the pencil code.
