TL;DR: Strong coupling involving three different types of resonances in plasmonic nanoarrays is shown: surface lattice resonances (SLRs), localized surface plAsmon resonances on single nanoparticles, and excitations of organic dye molecules.

TL;DR: This work shows lasing both in dark and bright modes of an array of silver nanoparticles combined with optically pumped dye molecules, opening a route to utilize all modes of plasmonic lattices, also the high-Q ones, for studies of strong light-matter interactions, condensation and photon fluids.

TL;DR: It is shown that coherence appears in proportion to the weight of the plasmonic component of the mode throughout the weak-to-strong coupling crossover, providing evidence for the hybrid nature of the normal modes.

TL;DR: In this article, a Bose-Einstein condensate of surface plasmon polaritons in lattice modes of a metal nanoparticle array is demonstrated, where the interaction of the nanoscale confined surface plasmons with a room-temperature bath of dye molecules enables thermalization and condensation in picoseconds.

TL;DR: This review of the concepts and the present state of theoretical studies of spin-imbalanced superfluidity, in particular the elusive Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, in the context of ultracold quantum gases focuses on settings that have been predicted to be favourable for the FFLO state, such as optical lattices in various dimensions and spin-orbit coupled systems.
