Description

Coexistence of different dynamical phases is a hallmark of glassy behavior, widely studied in classical systems via large deviation theory. Similar phase coexistence has been suggested in quantum many-body systems, but a systematic study has been challenging due to the lack of suitable methods. Here, I present a tensor network framework that enables large deviation analysis in large quantum systems. Using this approach, we identify first-order dynamical phase transitions in a monitored discrete-time many-body quantum dynamics. Importantly, this framework also allows us to access conditioned quantum states, providing a microscopic view of the dynamical phases and their coexistence. This talk will discuss both the methodology and the new insights it provides into quantum dynamical phase transitions.
