Quantum trajectories of dissipative time crystals
Albert Cabot, Leah Sophie Muhle, Federico Carollo, Igor Lesanovsky · Physical Review A · 2023
The authors address the boundary time-crystal transition at the level of individual quantum trajectories that result from continuous monitoring. Signatures of critical behavior and of the time-crystal phase are identified for the photon count signal and homodyne current, while each monitoring scheme is shown to imprint its own characteristic features.
