Observation of first- and second-order dissipative phase transitions in a two-photon driven Kerr resonator

Vincenzo Savona, Simone Frasca, Guillaume Beaulieu, Pasquale Scarlino, Fabrizio Minganti

In open quantum systems, dissipative phase transitions (DPTs) emerge from the interplay between unitary evolution, drive, and dissipation. While second-order DPTs have been predominantly investigated theoretically, first-order DPTs have been observed in si ...
