*School*

**7—16 January 2015**

The purpose of this winter school is to provide PhD students and young postdocs in the Nordic countries with introductory courses in a range of the most important topics in the field of theoretical particle physics. The school will provide a way to bring together students and young postdocs across different fields, research institutions and countries.

*Coordinators*: Paolo Di Vecchia, Konstantin Zarembo

*Workshop*

**25—27 February 2015**

This workshop series provides a forum where scientists in the Nordic countries working in the area of Statistical Physics can meet regularly. Topics covered include diffusion problems, physics of DNA and bio-molecules, population dynamics, pattern formation, non-equilibrium transport, bacterial motility, single-molecule kinetics, dynamics and structure of networks, statistical inference, Monte-Carlo simulation techniques, self-assembly, soft condensed matter (colloids, liquid crystals etc.), work relations and ﬂuctuation theorems, and many more.

*Coordinators*: Alberto Imparato, Ralf Eichhorn

**2—20 March 2015**

The cosmological constant and the physics behind dark energy that accelerates the expansion of the universe remain among the biggest mysteries in theoretical physics. An intriguing possibility is that these problems stem from extrapolating Einstein's General relativity from the Solar system to the far infrared cosmological scales. In the other extreme, at the ultraviolet regime Einstein's theory encounters notorious infinities resulting in spacetime singularities and obstacles to quantisation, which suggest new gravitational physics with possible repercussions to early universe physics. The program aims at establishing new links between fundamental physics and cosmological and astrophysical experiments from the fruitful interface of extended theories of gravity.

**9—13 March 2015**

Scientific recording of sunspots started with Galileo in 1609. Since Hale (1908) we know that sunspots are strong concentrations of magnetic field of up to 4000 gauss. They could be formed by subsurface magnetic flux tubes piercing the surface. Meanwhile, numerical simulations by many different groups suggest that strong magnetic fields could be generated in the bulk of the convection zone. This would mean that sufficiently strong magnetic fields may be generated not far from the surface. However, at the surface the magnetic field appears to be strongly concentrated into only a few isolated spots - in stark contrast to the more diffuse magnetic field beneath the surface. This is still a mystery.

**23—27 March 2015**

Renormalization group methods are a key element of theoretical particle physics and may also be central for constructing a fundamental theory of gravity, e.g., based on Weinberg’s asymptotic safety conjecture. The aim of this program is to bring together theorists and phenomenologists in order to discuss ideas related to the application of the renormalization group in quantum gravity and the consequences of asymptotic safety for cosmology, black holes and a possible ultraviolet completion of the standard model of particle physics including gravity.

*Coordinators*: Frank Saueressig, Dario Benedetti, Astrid Eichhorn

*Program*

**18 May — 12 June 2015**

The aim is to study quantum control and dynamics of few-particle systems in an active collaborative effort between experimentalists and theorists, as well as between recognized senior researchers and young investigators. The activity is motivated by recent advances in the physics of ultrafast phenomena in the femto- and attosecond time scale - a regime within reach of novel light sources. New insights into fundamental many-body physics are expected when ultrafast atomic and solid-state processes can be monitored in real time.
