Dynamical phase transitions, eigenstate thermalization, and Schrodinger cats... - David A. Huse

David A. Huse Princeton University October 15, 2013 An isolated quantum many-body system may be a reservoir that thermalizes its constituents. I will explore an example of the interplay of this thermalization and spontaneous symmetry-breaking, in the ferromagnetic phase of an infinite-range quantum Ising model. For a system of N spins, the barrier that must be crossed to flip the magnetization is of order N. The unitary quantum dynamics of this system can cross this barrier either by thermally activating it
