Dissipative phase transitions in open quantum manybody systems
Cristiano Ciuti (Laboratoire Matériaux et Phénomènes Quantiques, Université Paris Diderot et CNRS)
In the first part of the talk, I will introduce the general theoretical concepts behind the physics of dissipative phase transitions in open quantum manybody systems, with a particular emphasis on driven-dissipative lattices. These systems can be implemented using several platforms including superconducting quantum circuits and semiconductor microcavity lattices. In the second part of the talk, I will present recent theoretical results about critical phenomena in the 2D dissipative XYZ Heisenberg model and critical slowing down in the driven-dissipative Bose-Hubbard model. Perspectives and challenges will be discussed.
