The past 30 years have witnessed remarkable developments of microcavity exciton–
polaritons, which have made a great impact on photonics and optoelectronics from …

Exciton is the elementary excitation in semiconductors with energy close to E g, bound by
electron and hole. Spin is an intrinsic form of angular momentum carried by elementary …

We consider exciton polaritons in a zigzag chain of coupled elliptical micropillars subjected
to incoherent excitation. The driven-dissipative nature of the system along with the naturally …

Strong light–matter coupling of a photon mode to tightly bound Frenkel excitons in organic
materials has emerged as a versatile, room-temperature platform to study nonlinear many …

The topological spin-Hall effect causes different spins to propagate in opposite directions
based on Hermitian physics. The non-Hermitian skin effect causes the localization of a large …

Topological concepts have been applied to a wide range of fields in order to successfully
describe the emergence of robust edge modes that are unaffected by scattering or disorder …

Recent experiments showed the transfer of orbital angular momentum (OAM) from a
nonresonant laser onto an exciton-polariton condensate, despite earlier views that the …

Non-Hermitian topological corner modes can be formed in exciton-polariton lattices under
nonresonant pumping. Signals propagating in the bulk of the system can travel around …

Collective (elementary) excitations of quantum bosonic condensates, including condensates
of exciton polaritons in semiconductor microcavities, are a sensitive probe of interparticle …

We investigate the optical orientation, polarization pinning, and depolarization of optically
confined semiconductor exciton-polariton condensates. We perform a complete mapping of …
