Thermodynamics and CP-odd transport in Holographic QCD with Finite Magnetic Field

Understand

We consider a bottom-up holographic model of QCD at finite temperature T and magnetic field B, and study dependence of thermodynamics and CP-odd transport on these variables.

• As the magnetic field couples to the flavor sector only, one should take the Veneziano limit where the number of flavors and colors are large while their ratio is kept fixed.
• We investigate the corresponding holographic background in the approximation where the ratio of flavors to colors is finite but small.
• We demonstrate that B-dependence of the entropy of QCD is in qualitative agreement with the recent lattice studies.
