Temperature and quark density effects on the chiral condensate: an AdS/QCD study

Understand

We investigate the dependence of the chiral condensate $<\bar qq>$ on the temperature and quark density using the soft-wall holographic model of QCD, adopting geometries with black holes at finite temperature and quark chemical potential $\mu$.

• We find that, for $\mu$ below a critical value, increasing the temperature the condensate decreases and vanishes at a temperature $\tilde T\simeq 210$ MeV (at $\mu=0$).
• An analogous behaviour is observed increasing the chemical potential at fixed temperature.
• These results agree with the findings obtained by other methods.
