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

Microcavity polaritons are light-matter quasiparticles that arise from the strong coupling
between excitons and photons confined in a semiconductor microcavity. They are typically …

Giant Rydberg excitons with principal quantum numbers as high as n= 25 have been
observed in cuprous oxide (Cu2O), a semiconductor in which the exciton diameter can …

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 …

Low‐dimensional light‐emitting materials have been actively investigated due to their
unprecedented optical and optoelectronic properties that are not observed in their bulk …

Topological insulators are a class of electronic materials exhibiting robust edge states
immune to perturbations and disorder. This concept has been successfully adapted in …

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 …

We predict the existence of non-Hermitian topologically protected end states in a one-
dimensional exciton-polariton condensate lattice, where topological transitions are driven by …

We consider theoretically a system of exciton-polariton micropillars arranged in a
honeycomb lattice. The naturally present TE-TM splitting and an alternating Zeeman …
