Description

This workshop is funded by the newly established research training group RTG 2522 and aims to bring together researchers from different areas of theoretical physics who study manifestations and phenomena of strongly-interacting field theories, in order to allow for a transfer of knowledge and methods. This year's workshop plans to put a special emphasis on symmetry breaking and phase transitions, quantum field theory in and out of equilibrium, inhomogeneous condensates and fermionic systems.

The workshop intends to be a platform to stimulate a cross-fertilization between discrete and continuum approaches to strongly-interacting field theories - spanning the range from lattice gauge theory, functional renormalization group methods to gauge/gravity dualities.

  Dynamics on the edge: charge fractionalization and anyonic exclusion
  
  Equilibration of isolated quantum systems has attracted much attention recently. Due to their integrability, one-dimensional systems often equilibrate towards a non-thermal steady state. In coupled quantum Hall edge states, the approach towards such a non-equilibrium steady state can be understood in terms of charge fractionalization, i.e. the decomposition of injected charges into eigenmodes propagating at different velocities. The method of non-equilibrium bosonization allows to describe such equilibration, distinguishing the regimes of quasi-particle creation and local equilibration. Generalizing to anyons on fractional quantum Hall edges, steady state current fluctuations can be related to the probability of anyons excluding each other spatially.

  Crystalline chiral condensates in dense quark matter
  
  In the past few years a growing consensus has been building around the idea that a spatially inhomogeneous chiral condensate may form in dense quark matter. In this talk, I will give a brief historical overview and review some recent developments on the characterization of such crystalline condensates using effective models for describing of QCD at finite density.

  The melonic large N limit: from SYK to tensor field theory
  
  I will summarize the structure and scope of the so-called melonic large N expansion, which typically governs the large N behaviour of theories involving higher rank tensors. Compared to vector and matrix theories, What distinguishes it from the large N expansions of vector or matrix theories is that it is dominated by a non-trivial family of Feynman diagrams -- the melon diagrams -- which remains explicitly summable in a variety of situations. This provides a new analytical window into non-perturbative aspects of quantum theory, which has been taken advantage of to investigate strongly-interacting fermionic disordered systems (SYK model) and higher-dimensional generalizations.
