The interaction between molecular electronic transitions and electromagnetic fields can be
enlarged to the point where distinct hybrid light–matter states, polaritons, emerge. The …

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 …

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 …

Exciton polaritons, the part-light and part-matter quasiparticles in semiconductor optical
cavities, are promising for exploring Bose–Einstein condensation, non-equilibrium many …

Bound states in the continuum (BICs),–are peculiar topological states that, when realized in
a planar photonic crystal lattice, are symmetry-protected from radiating in the far field despite …

Strong light-matter interaction enriches topological photonics by dressing light with matter,
which provides the possibility to realize active nonlinear topological devices with immunity to …

Topology is central to understanding and engineering materials that display robust physical
phenomena immune to imperfections. Different topological phases of matter are …

The quest for realizing novel fundamental physical effects and practical applications in
ambient conditions has led to tremendous interest in microcavity exciton polaritons working …

The “marriage” of light (ie, photon) and matter (ie, exciton) in semiconductors leads to the
formation of hybrid quasiparticles called exciton polaritons with fascinating quantum …
