Continuous time crystals as a PT symmetric state and the emergence of critical exceptional points
Yuma Nakanishi, Ryo Hanai, Tomohiro Sasamoto
Continuous time-translation symmetry is often spontaneously broken in open quantum systems, and the condition for their emergence has been actively investigated. However, there are…

Phase Transitions in Nonreciprocal Driven-Dissipative Condensates
Ron Belyansky, Cheyne Weis, Ryo Hanai +2
We investigate the influence of boundaries and spatial nonreciprocity on nonequilibrium driven-dissipative phase transitions. We focus on a one-dimensional lattice of nonlinear bos…
