Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

Lead-halide perovskites are generally excellent light emitters and can have larger exciton
binding energies than thermal energy at room temperature, exhibiting great promise for …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

Topology describes properties that remain unaffected by smooth distortions. Its main
hallmark is the emergence of edge states localized at the boundary between regions …

Certain lattice wave systems in translationally invariant settings have one or more spectral
bands that are strictly flat or independent of momentum in the tight binding approximation …

Exciton polaritons, with extremely low effective mass, are regarded as promising candidates
to realize Bose–Einstein condensation in lattices for quantum simulations towards room …

Exotic phases of matter can emerge from the interplay between strong electron interactions
and non-trivial topology. Materials that have non-dispersing bands in their electronic band …

In this review we discuss the works in the area of quantum simulation and many-body
physics with light, from the early proposals on equilibrium models to the more recent works …

Although kinetic energy of a massive particle generally has quadratic dependence on its
momentum, a flat, dispersionless energy band is realized in crystals with specific lattice …
