Non-equilibrium dynamics of Goldstone excitation from holography

Abstract By using the holographic approach, we investigate the interplay between the order parameter and Goldstone modes in the real-time dynamics of the chiral phase transition. By quenching the system to a different thermal bath and obtaining different kinds of initial states, we solve the real-ti...

Description
Summary:Abstract By using the holographic approach, we investigate the interplay between the order parameter and Goldstone modes in the real-time dynamics of the chiral phase transition. By quenching the system to a different thermal bath and obtaining different kinds of initial states, we solve the real-time evolution of the system and find that an additional prethermalization stage emerges at non-critical temperature after introducing the Goldstone modes. Some basic properties related to this additional prethermalization stage have been discussed in detail. More interestingly, an additional scaling relation is observed, indicating the appearance of a non-thermal fixed point in the dynamical region.
