Inhomogeneous phases in effective quark models — •Achim Heinz, Francesco Giacosa, Marc Wagner, and Dirk H. Rischke — Institut of Theoretical Physics, Frankfurt am Main, Germany

Chiral symmetry is a symmetry of the QCD Lagrangian, which is spontaneously broken due to nonperturbative phenomena. As a consequence, a chiral condensate, which corresponds to a vacuum's condensate of quark-antiquark pairs, emerges. Usually, this condensate is treated as constant over space, but analytic as well as numerical studies show that an inhomogenous condensation is favored at high density. However, in most cases it is not possible to calculate analytically the emergence of inhomogeneous condensation. Therefore it is important to improve numerical methods: in the talk, we present a new numerical approach which is capable to reproduce well-known analytic results in 1+1 as well as in 1+3 dimensions. We also outline which studies can be performed with this method in the near future.
