The appearance of quantized vortices in the classical “rotating bucket” experiments of liquid
helium and ultracold dilute gases provides the means for fundamental and comparative …

Microcavity exciton‐polaritons are attractive quantum quasi‐particles resulting from strong
light–matter coupling in a quantum‐well‐cavity structure. They have become one of the most …

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 …

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

We propose a scheme for producing and manipulating quantized exciton-polariton vortices
in the higher-order topological corner modes of a two-dimensional array of micropillars. By …

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 …

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

Periodic temporal modulation of Hamiltonians can induce geometrical and topological
phenomena in the dynamics of quantum states. Using the interference between two lasers …
