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

By C. A. Ballon Bayona, Kasper Peeters and Marija Zamaklar

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.Comment: 23 pages, 12 figures; v2: references adde
