Résumé |
Non-reciprocal interactions and activity are ubiquitous in classical systems far
from equilibrium, from living and soft matter to ecology and optics. They give
rise to distinctive collective phenomena and phase transitions. In this talk, I
will discuss how non-reciprocal and active dynamics can be realised in quantum
systems through engineered coupling to an external environment. I will first
present our results on interacting non-reciprocal fermions and their dissipative
phase transitions. I will then introduce three minimal models of an active quantum
particle, exploring how activity manifests in the quantum regime. |
