Information dynamics and symmetry breaking in generic monitored -symmetric open quantum systems
Jacob Hauser, Ali Lavasani, Sagar Vijay +1
We investigate the steady-state phases of generic -symmetric monitored, open quantum dynamics. We describe the phases systematically in terms of both information-theo…

Dissipative Dynamical Phase Transition as a Complex Ising Model
Stephen W. Yan, Diego Barberena, Matthew P. A. Fisher +1
We investigate a quantum dynamical phase transition induced by the competition between local unitary evolution and dissipation in a qubit chain with a strong, on-site $\mathbb{Z}_2…

Postselection in lattice bosons undergoing continuous measurements
Diego Barberena, Matthew P. A. Fisher
We study in detail the postselection problem in a specific model: bosons hopping on a lattice subjected to continuous local measurements of quadrature observables. We solve the mod…
