Inverse magnetic catalysis in holographic models of QCD

We study the effect of magnetic field B on the critical temperature T-c of the confinement-deconfinement phase transition in hard-wall AdS/ QCD, and holographic duals of flavored and unflavored N = 4 super-Yang Mills theories on R-3 x S-1. For all of the holographic models, we find that Tc (B) decreases with increasing magnetic field B << T-2, consistent with the inverse magnetic cat alysis recently observed in lattice QCD for B less than or similar to 1 GeV2. We also predict that, for large magnetic field B >> T-2, the critical temperature Tc (B), eventually, starts to increase with increasing magnetic field B >> T-2 and asymptotes to a constant value.
