Holographic phase transitions at finite chemical potential

Understand

Recently holographic techniques have been used to study the thermal properties of N=2 super-Yang-Mills theory, with gauge group SU(Nc) and coupled to Nf << Nc flavours of fundamental matter, at large Nc and large 't Hooft coupling.

• Here we consider the phase diagram as a function of temperature and baryon chemical potential mu.
• For fixed mu < Nc Mq there is a line of first order thermal phase transitions separating a region with vanishing baryon density and one with nonzero density.
• For fixed mu > Nc Mq there is no phase transition as a function of the temperature and the baryon density is always nonzero.
