A non-homogeneous ground state of the low-temperature Sakai-Sugimoto model

arXiv:1104.2291 · doi:10.1007/JHEP06(2011)092

Abstract

We study the instability of the low-temperature QCD vacuum at large-N_c due to an axial chemical potential, using the holographic Sakai-Sugimoto model. We explicitly construct the ground state of the theory, which corresponds to a translationally non-invariant configuration.
