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…
Interaction induced bi-skin effect in an exciton-polariton system
Xingran Xu, Huawen Xu, S. Mandal +3
The non-Hermitian skin effect can be realized through asymmetric hopping between forward and backward directions, where all the modes of the system are localized at one edge of a f…
Non-reciprocal transport of Exciton-Polaritons in a non-Hermitian chain
S. Mandal, R. Banerjee, Elena A. Ostrovskaya +1
We consider theoretically the dynamics of exciton-polaritons in a zigzag chain of coupled elliptical micropillars subjected to incoherent excitation. The driven-dissipative nature…
Coupling between Exciton-Polariton Corner Modes through Edge States
R. Banerjee, S. Mandal, T. C. H. Liew
Recently realized higher order topological insulators have taken a surge of interest among the theoretical and experimental condensed matter community. The two-dimensional second o…
One-way reflection-free exciton-polariton spin filtering channel
S. Mandal, R. Banerjee, T. C. H. Liew
We consider theoretically exciton-polaritons in a strip of honeycomb lattice with zigzag edges and it is shown that the interplay among the spin-orbit coupling, Zeeman splitting, a…
On the possibility of a terahertz light emitting diode based on a dressed quantum well
S. Mandal, K. Dini, O. V. Kibis +1
We consider theoretically the realization of a tunable terahertz light emitting diode from a quantum well with dressed electrons placed in a highly doped p-n junction. In the consi…
