Non-Hermitian trapping of Dirac exciton-polariton condensates in a perovskite metasurface
Mikhail Masharin, Igor Chestnov, Andrey Bochin +9
Massless Dirac particles avoid trapping due to their exceptional tunneling properties manifested in the so-called Klein paradox. This conclusion stems from the conservative treatme…
Reservoir neuromorphic computing based on spin-orbit coupling in an organic crystal resonator
Teng Long, Yibo Deng, Xuekai Ma +5
Neuromorphic computing is at the basis of the recent progress in artificial intelligence. But the progress is accompanied with increasing demands in computational resources and pow…
Exciton interaction induced spin splitting in MoS monolayer
Yao Li, G. Li, Xiaokun Zhai +11
By pumping nonresonantly a MoS monolayer at K under a circularly polarized cw laser, we observe exciton energy redshifts that break the degeneracy between B excitons with…
Circular polarization reversal of half-vortex cores in polariton condensates
Matthias Pukrop, Stefan Schumacher, Xuekai Ma
Vortices are topological objects carrying quantized orbital angular momentum and have been widely studied in many physical systems for their applicability in information storage an…
Split-ring polariton condensates as macroscopic two-level quantum systems
Yan Xue, Igor Chestnov, Evgeny Sedov +5
Superposition states of circular currents of exciton-polaritons mimic the superconducting flux qubits. The phase of a polariton fluid must change by an integer number of , when…
Collective state transitions of exciton-polaritons loaded into a periodic potential
K. Winkler, O. A. Egorov, I. G. Savenko +9
We study the loading of a nonequilibrium, dissipative system of composite bosons -- exciton polaritons -- into a one dimensional periodic lattice potential. Utilizing momentum reso…
Oscillatory dynamics of non-equilibrium dissipative exciton-polariton condensates in weak-contrast lattices
X. Ma, I. Yu. Chestnov, M. V. Charukhchyan +2
We study nonlinear dynamics of exciton-polaritons in an incoherently pumped semiconductor microcavity with embedded weak-contrast lattice and coupled to an exciton reservoir. We el…
