Title:
Holographic Quenches at Zero Temperature
Speaker:
Abstract:
We discuss quenches performed at zero initial temperature at strongly coupled 2+1 dimensional theories in a gapped phase, utilizing holography to investigate both local observables and the entanglement entropy. We compare and contrast our results with existing studies of lower dimensional spin chain systems. The final state is characterized by oscillatory behavior of local and non-local observables, rather than decay towards equilibrium. In an attempt to characterize the late-time state of this scenario we check a number of notions of thermalization. Interestingly, we find no evidence for thermalization for our chosen parameters and initial states, even in the weakest sense.
