Electrically reconfigurable extended lasing state in an organic liquid-crystal microcavity
Dmitriy Dovzhenko, Luciano Siliano Ricco, Krzysztof Sawicki +12
Small-footprint, low-power arrays of coupled coherent emitters with the capability of near- and far-field engineering and coherence control are highly sought after to meet modern n…
Non-Hermitian skin effect induced by Rashba-Dresselhaus spin-orbit coupling
Pavel Kokhanchik, Dmitry Solnyshkov, Guillaume Malpuech
1D chains with non-reciprocal tunneling realizing the non-Hermitian skin effect (NHSE) have attracted considerable interest in the last years whereas their experimental realization…
Design of a room-temperature topological exciton-polariton laser in a ZnO/TiO-photonic crystal slab
I. Septembre, C. Leblanc, L. Hermet +4
We propose theoretically a scheme to get a room-temperature 2D topological exciton-polariton laser with propagating topological lasing modes. The structure uses guided modes in a p…

Ismaël Septembre, Julia S. Meyer, Dmitry D. Solnyshkov +1
We study theoretically analog multi-terminal Josephson junctions formed by gapped superfluids created upon resonant pumping of cavity exciton-polaritons. We study the -like band…

We have used a polarized microluminescence technique to investigate photocarrier charge and spin transport in n-type depleted GaAs nanowires ( cm doping le…
Annihilation of exceptional points from different Dirac valleys in a 2D photonic system
M. Król, I. Septembre, P. Oliwa +13
Topological physics relies on the existence of Hamiltonian's eigenstate singularities carrying a topological charge, such as quantum vortices, Dirac points, Weyl points and -- in n…
Giant effective Zeeman splitting in a monolayer semiconductor realized by spin-selective strong light-matter coupling
T. P. Lyons, D. J. Gillard, C. Leblanc +11
Strong coupling between light and the fundamental excitations of a two-dimensional electron gas (2DEG) are of foundational importance both to pure physics and to the understanding…

C. Leblanc, G. Malpuech, D. D. Solnyshkov
We derive semiclassical equations of motion for an accelerated wavepacket in a two-band system. We show that these equations can be formulated in terms of the static band geometry…

We study the formation of topological defects (quantum vortices) during the formation of a 2D polariton condensate at the point of a honeycomb lattice via the Kibble-Zurek mech…

A driven-dissipative nonlinear photonic system (e.g. exciton-polaritons) can operate in a gapped superfluid regime. We theoretically demonstrate that the reflection of a linear wav…

The usual concepts of topological physics, such as the Berry curvature, cannot be applied directly to non-Hermitian systems. We show that another object, the quantum metric, which…
