Abstract Distributed Bragg reflectors (DBRs) are primarily used in lasers and telecommunications. Liquid film deposition of DBRs holds great promise for expanding their utilization in environmental friendly, low‐cost, and large‐area applications.

Understanding the sub-picosecond dynamics of driven-dissipative condensates of interacting bosons is challenging. Here the authors combine a lattice of plasmonic nanoparticles with a dye molecule solution in strong coupling and reveal distinct lasing

Because of their bosonic nature, exciton-polaritons can condense into a single macroscopic coherent state under the right conditions. This process is uniquely characterized by its out-of-equilibrium nature, which gives rise to some distinctions when

Superfluidity---the suppression of scattering in a quantum fluid at velocities below a critical value---is one of the most striking manifestations of the collective behaviour typical of Bose-Einstein condensates. This phenomenon, akin to superconduct

Although only a handful of organic materials have shown polariton condensation, their study is rapidly becoming more accessible. The spontaneous appearance of long-range spatial coherence is often recognized as a defining feature of such condensates.
