Dissipation Induced Structural Instability and Chiral Dynamics in a Quantum Gas

Understand

Dissipative and unitary processes define the evolution of a many-body system.

• Their interplay gives rise to dynamical phase transitions and can lead to instabilities.
• We discovered a non-stationary state of chiral nature in a synthetic many-body system with independently controllable unitary and dissipative couplings.
• Our experiment is based on a spinor Bose gas interacting with an optical resonator.
