Almost a century ago Einstein’s seminal paper 'Cosmological Considerations in the General Theory of Relativity' (2 August 1917) proposed a game changing addition to his theory of general relativity: Lambda, the cosmological constant. Since then, and in particular from the remarkable experimental data gathered during the last two decades, the cosmological constant has gone from a theoretical sideline to a central feature of research in cosmology and quantum gravity, including the effective Λ of inflation, the observed Λ of the late time acceleration of our universe, and the negative Λ of the gauge/gravity correspondence in string theory. Theoreticians and philosophers have been fascinated and aggravated by 'the Lambda Problem' for a century. The advent of precision cosmology has made this an issue of practical relevance, and this workshop will be productive through critiquing and advancing theoretical approaches within the constraints of observations.

The program explores recent developments in describing the dynamics of strongly-coupled field theories using the notion of fundamental, quantum bounds on transport, and their interplay with quantum chaos. By bringing together international leaders in condensed matter and high-energy physics, we aim at enhancing our current understanding by combining experimental results and the various theoretical, non-perturbative approaches to these problems. Participants will include experts in thermoelectric transport experiments, hydrodynamics, gauge/gravity duality, condensed matter and conformal field theory.

Magnetic helicity is a conserved quantity in ideal MHD and is also a topological invariant. Due to these properties, it plays special roles for the operation of the global solar dynamo, and in the release of solar eruptive events, but both of these related processes remain poorly understood. On both themes, theoretical models would benefit from being validated and constrained with observational data, and the increasing amounts of observational data could be more efficiently used as basis to improve the models. The abundant observational data pouring in from various sources poses its own challenges and sometimes cross-calibrations are lacking. This program will bring together solar observers and dynamo theorists to work on these topics. We aim to obtain crucial new knowledge on the operation of the global solar dynamo itself, but also how it drives eruptive events which then are observed as space weather.

Quantum Information Science is a major frontier of modern science and technology, exploring physical situations that are classically impossible. An important technological application, already available today, is secure quantum key distribution realized by spatially separated entangled quantum states. This program will be centered around new fundamental physical questions that will emerge from successful current and future quantum technologies. The focus will be on effects and phenomena that appear already in low-dimensional quantum systems, and which are (or may soon be) experimentally realized.

Physical systems look different when observed at different resolutions: what appears as a continuum liquid to the naked eye becomes a cluster of jiggling atoms when observed at the resolution of an electron microscope. Effective field theory provides a description of physics in terms of degrees of freedom appropriate to a given resolution. Over the last couple of decades, physicists have developed effective field theory tools which, to a large extent, unify fields as diverse as atomic and condensed-matter physics, particle and nuclear physics, and cosmology. The ensuing interaction between different branches of physics has never been as fruitful as it is now. The aim of this program is to give a new impulse to a further development of this exciting interdisciplinary field. We bring together leading practitioners working on effective theories of quantum phases of matter across several branches of physics. Our goal is to map out important open problems with broad relevance and look for new directions towards their solution, to reinvigorate existing collaborations and foster new connections.

This Nordita Program is devoted to theoretical and observational studies of the interstellar medium of galaxies across cosmic time, and to their implications in shaping future line-intensity mapping experiments which have recently generated a tremendous interest in the Community of astrophysicists and cosmologists. The program is particularly timely because the advent of new facilities, such as ALMA full array, JWST (launch spring 2019), and E-ELT (2024), will provide a wealth of high resolution multi-wavelength spectroscopic data on the ISM of galaxies across cosmic time. Moreover, the program will bring together experts from different areas as we aim gathering astrophysicists, working on galactic and extragalactic observation, theoreticians devising simulations, astrochemists, and cosmologists interested in the large scale structure of the Universe. The program has been conceived with a bottom-up structure that, from ~pc scales, relevant for star formation, will zoom-out up to ~Mpc scales relevant for intensity mapping experiments.

In recent years there have been exciting new developments at the interface between elliptic integrable systems, special functions and quantum field theory. The aim of this workshop is to obtain a better understanding of the emerging links between these topics and to help bring out further unexpected connections in the future. This will be achieved by bringing together researchers from diverse areas in mathematics and physics, for a week of lectures and informal discussions. The workshop is the continuation of a series (Kyoto 2004, Bonn 2008, Leiden 2013, Vienna 2017). It is a satellite meeting of String Math 2019, which takes place on Uppsala 1-5 July. The main themes of the meeting are: Elliptic integrable systems, Elliptic hypergeometric functions, Elliptic and classical Painlevé equations, and New special functions emerging from quantum field theory

Growing amount of molecular biological data combined with current advances in modeling of complex systems provide unprecedented opportunities to understand biological evolution in a quantitative way. A quantitative description of an evolving system is the first step towards prediction and control, and it opens new exciting directions for highly interdisciplinary research. The central questions are: (i) to what degree we can predict the outcome of biological evolution, (ii) what features of the system are predictable and (iii) which features confer predictive value for a quantitative description of the system. This program brings together theoretical and experimental physicists, experimental biologists with an interest in quantitative modelling and mathematicians with interest in biological systems. We aim to create a dialog between researchers of different fields and to inspire future collaborations. In addition, further developments in this field would have significant translational impacts, e.g., by optimizing vaccines against evolving viruses, designing strategies for personalized cancer therapy and by providing insights to the problem of antibiotic resistance.

The conference will cover cutting-edge non-perturbative methods in quantum field theory, as well as mathematical aspects of integrability and its more traditional applications in condensed-matter physics and statistical mechanics. Solvable models play a valuable a role in theoretical physics, as they illustrate general concepts in a simpler setting and provide insights into the qualitative features of more complex phenomena.

In the last few years there has been renewed interest in QCD and hadronic dynamics using holographic gauge/gravity duality, resurge of the large N methods, progress in string models, integrability, unitarity and bootstrap and more. Also, many new experimental results were reported by ALICE at LHC regarding collectivization in pp and pA collisions, by LHCb at CERN and the B- and C-factories regarding the existence of exotics and the spectroscopy of heavy-light systems, and more recently the reporting of 2 neutron star mergers by the LIGO collaboration and its constraint on the nuclear dense equation of state. The conference will bring together practitioners of these interdisciplinary fields to discuss these exciting new developments, and explore the relevance of the holographic framework for addressing these observations.

Recent advances in the band theory of crystalline materials have singled out topology as a key ingredient in the modern classification of matter, with major impact on measurable electronic properties. Topological band theory has also grown into an emerging paradigm in many areas of physics, and is now used to characterize metamaterials, including photonic, atomic, acoustic, and elastic systems, in both the quantum and classical regimes. As our understanding of topology in physics widens, the incorporation of out-of-equilibrium phenomena is gaining in importance.
