Topological enhancement of exciton-polariton coherence with non-Hermitian morphing
Ruiqi Bao, Huawen Xu, Wouter Verstraelen +1
The non-Hermitian skin effect (NHSE) has been intensely investigated over the past few years and has unveiled new topological phases, which have no counterparts in Hermitian system…
Spin-polarized antichiral exciton-polariton edge states
Ruiqi Bao, S. Mandal, Huawen Xu +3
We consider theoretically a system of exciton-polariton micropillars arranged in a honeycomb lattice. The naturally present TE-TM splitting and an alternating Zeeman splitting, whe…
Non-reciprocal Exciton-Polariton Ring Lattices
Huawen Xu, Kevin Dini, Xingran Xu +3
Recent experiments have shown the transfer of orbital angular momentum (OAM) from a non-resonant laser onto an exciton-polariton condensate, despite earlier views that the phase in…
Non-Hermitian topological exciton-polariton corner modes
Xingran Xu, Ruiqi Bao, Timothy C. H. Liew
We theoretically study two-dimensional exciton-polariton lattices and predict that non-Hermitian topological corner modes can be formed under non-resonant pumping. As a generalizat…
Optically induced topological spin-valley Hall effect for exciton polaritons
R. Banerjee, S. Mandal, T. C. H. Liew
We consider exciton-polaritons in a honeycomb lattice of micropillars subjected to circularly polarized () incoherent pumps, which are arranged to form two domains in the…
From the topological spin-Hall effect to the non-Hermitian skin effect in an elliptical micropillar chain
S. Mandal, R. Banerjee, T. C. H. Liew
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 l…
