Abstract

We present simple toy models of mixed state phases and phase transitions beyond thermal transitions, observed from the steady state structure of strongly symmetric local Lindbladians. To diagnose these mixed state phases and phase transitions, we introduce a local marginal fidelity that serves as a proxy for the fidelity correlator, and can be computed from tomography on a finite number of sites.
