Low-Dimensional Chiral Physics: Magnetic Catalysis — •Daniel David Scherer and Holger Gies — Theoretisch-Physikalisches Institut, Friedrich-Schiller-Universität Jena, Jena (Germany)

Magnetic catalysis describes the enhancement of symmetry breaking quantum fluctuations in chirally symmetric quantum field theories by the coupling of fermionic degrees of freedom to a magnetic background configuration. We use the functional renormalization group to investigate this phenomenon for interacting Dirac fermions moving in 2+1 dimensional space-time and provide for a clear renormalization-group picture.
