Description
We will discuss chiral phase transition in the soft-wall AdS/QCD model, by the bottom-up approach. The phase structure in the mass plane is extracting by analyzing the order parameter. It turns out to be consistent with the so called 'Columbia plot'. The in-medium properties of pions, as the Goldstone bosons, are investigated, as well. Qualitatively, the results are consistent with the finite temperature chiral perturbation theory. Finally, the real-time dynamics of chiral phase transition is studied. Interestingly, for a large class of initial states, the system would linger over a quasi-steady state for a certain period of time before the thermalization. It is suggested that the interesting phenomenon, known as prethermalization, has been observed in the framework of holographic models.
