“…Conceptually, this corresponds to considering a perfect cavity prepared with an initial finite excitation density and then asking for the ground state. This model can also describe the BEC of exciton polaritons—superpositions of microcavity photons and excitons—in the limit of a very good cavity …”

The Dicke model describes the coupling between a quantized cavity field and a large ensemble of two‐level atoms. When the number of atoms tends to infinity, this model can undergo a transition to a superradiant phase, belonging to the mean‐field Ising universality class. The superradiant transition was first predicted for atoms in thermal equilibrium and was recently realized with a quantum simulator made of atoms in an optical cavity, subject to both dissipation and driving. This progress report offers an introduction to some theoretical concepts relevant to the Dicke model, reviewing the critical properties of the superradiant phase transition and the distinction between equilibrium and nonequilibrium conditions. In addition, it explains the fundamental difference between the superradiant phase transition and the more common lasing transition. This report mostly focuses on the steady states of atoms in single‐mode optical cavities, but it also mentions some aspects of real‐time dynamics, as well as other quantum simulators, including superconducting qubits, trapped ions, and using spin–orbit coupling for cold atoms. These realizations differ in regard to whether they describe equilibrium or nonequilibrium systems.

“…The exciton-exciton Coulomb repulsion provides an effective Kerr nonlinearity U in the range of a few tenths of μeV. Polaritons achieve lifetimes τ p =h/κ ranging between 10 and 100 ps in state-of-the-art structures [50], thus fulfilling the condition U κ J . For strong confinement, polaritons are accurately modeled as two coupled nonlinear oscillators in the presence of driving fields and dissipation [38,51].…”

We theoretically study the emission statistics of a weakly nonlinear photonic dimer during coherent oscillations. We show that the phase and population dynamics allow to periodically meet an optimal squeezing condition resulting in a strongly nonclassical emission statistics. By considering an exciton-polariton Josephson junction driven resonantly by a pulsed classical source, we show that a sizable antibunching should emerge in such a semiconductor system where intrinsic nonclassical signatures have remained elusive to date.

“…The thermodynamic process alters the free-energy landscape and may result in relaxation paths into new (meta)stable structures. This exploration of process-accessible structures has just begun to be explored by simulation [74] and experiments. [75,76] Coarse-grained particle-based simulations will provide important insights for continuum approaches by, for example, providing the Onsager coefficients that relate the dynamics of underlying motion of the extended macromolecules to the time evolution of collective properties.…”

This article aims to stimulate research on non‐equilibrium macromolecular systems, as nowadays a large toolbox to synthesize tailored macromolecules is available. A large variety of characterization methods covering a broad spectrum of length and timescales allows researchers to follow and also manipulate macromolecular systems on their paths toward equilibrium. These possibilities are paralleled by the development of new concepts of the statistical physics of non‐equilibrium phenomena in macromolecular systems as well as new models and algorithms for computer simulation.
