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.
