Spectral theory of Liouvillians for dissipative phase transitions

F Minganti, A Biella, N Bartolo, C Ciuti - Physical Review A, 2018 - APS

Bistability versus metastability in driven dissipative Rydberg gases

F Letscher, O Thomas, T Niederprüm, M Fleischhauer… - Physical Review X, 2017 - APS
We investigate the possibility of a bistable phase in an open many-body system. To this end,
we discuss the microscopic dynamics of a continuously off-resonantly driven Rydberg lattice …
