DY 31: Focus Session: Nonequilibrium Collective Behavior in Open Classical and Quantum Systems

Donnerstag, 20. März 2025, 09:30–12:45, H37

Nonequilibrium classical and quantum systems coupled to thermal or (driven) non-equilibrium environments have recently been shown to exhibit rich collective phenomena and phase transitions without equilibrium counterparts. From the classical side, intriguing examples are flocking and phase separation in active matter, but also patterns and bifurcations in driven-diffusive systems and spontaneous parity-time symmetry breaking in systems involving nonreciprocal couplings. From the quantum side much interest has been devoted, e.g., to ordering and phase transitions in non-equilibrium steady states, the formation of time crystals, superradiance, as well as phase transitions or critical behavior in time. The symposium and the accompanying focus session is devoted to connections between the quantum and the classical realms, as they have been explored recently both in theory and experiment.
