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

In this review, we present the theoretical foundations and first-principles frameworks to
describe quantum matter within quantum electrodynamics (QED) in the low-energy regime …

Solution-processable semiconductor lasers have been a long-standing challenge for next-
generation displays, light sources, and communication technologies. Metal halide …

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 …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

Perovskite crystals—with their exceptional nonlinear optical properties, lasing and
waveguiding capabilities—offer a promising platform for integrated photonic circuitry within …

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

Lead halide perovskites have emerged as excellent optical gain materials for solution-
processable and flexible lasers. Recently, continuous-wave (CW) optically driven lasing was …

Nonlinear optics has undergone dramatic developments in the past 60 years, which has
revolutionized the photonic and optoelectronic fields with many essential applications such …

Unlike conventional laser, the topological laser is able to emit coherent light robustly against
disorders and defects because of its nontrivial band topology. As a promising platform for …
