Tomas Brauner: Chiral soliton lattice in dense quark matter

Abstract

It is common lore to assume that the ground state of a given quantum field theory is uniform. Understanding the conditions under which a spatially nontrivial structure can arise from local translationally invariant interactions is an intriguing problem in quantum many-body physics. In the first part of the talk, I will review some known mechanisms for formation of nonuniform order. Then I will focus on the lattice of topological solitons that is induced in quark matter by strong magnetic fields. The universality of this chiral soliton lattice (CSL) order is underlined by the mathematical analogy between dense quark matter and chiral magnets. In the end, I will give a brief overview of the various realizations of CSL in quark matter, discovered in the recent years.
