Chirality by dissipation Quantum many-body systems can display exotic dynamics in the presence of dissipation. Dogra et al. studied such dynamics in a system consisting of an atomic Bose-Einstein condensate located in an optical cavity and exposed to a standing wave of laser light. Light scattering off the atomic cloud and into the cavity resulted in two distinct, spatially patterned collective modes for the atoms. When the researchers then introduced dissipation to couple the two modes, the… 

Emerging Dissipative Phases in a Superradiant Quantum Gas with Tunable Decay

Exposing a many-body system to external drives and losses can transform the nature of its phases and opens perspectives for engineering new properties of matter. How such characteristics are related

This work explores the influence of dissipation on a paradigmatic driven-dissipative model where a collection of two level atoms interact with both quadratures of a quantum cavity mode and shows that, surprisingly, the tricritical points exhibit anomalous finite fluctuations, as opposed to standard trICritical points arising in ^{3}He-^{4}He mixtures.
