Direct Measurement of a Non-Hermitian Topological Invariant in a Hybrid Light-Matter System
Rui Su, Eliezer Estrecho, Dąbrówka Biegańska +7
Topology is central to understanding and engineering materials that display robust physical phenomena immune to imperfections. Different topological phases of matter are characteri…
Collective excitations of exciton-polariton condensates in a synthetic gauge field
D. Biegańska, M. Pieczarka, E. Estrecho +7
Collective (elementary) excitations of quantum bosonic condensates, including condensates of exciton polaritons in semiconductor microcavities, are a sensitive probe of interpartic…
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…
Long-lived populations of momentum- and spin-indirect excitons in monolayer WSe
Shao-Yu Chen, Maciej Pieczarka, Matthias Wurdack +6
Monolayer transition metal dichalcogenides are a promising platform to investigate many-body interactions of excitonic complexes. In monolayer tungsten diselenide, the ground-state…
Two-dimensional GaO glass: a large scale passivation and protection material for monolayer WS
Matthias Wurdack, Tinghe Yun, Eliezer Estrecho +14
Atomically thin transition metal dichalcogenide crystals (TMDCs) have extraordinary optical properties that make them attractive for future optoelectronic applications. Integration…
Low-energy collective oscillations and Bogoliubov sound in an exciton-polariton condensate
E. Estrecho, M. Pieczarka, M. Wurdack +6
We report the observation of low-energy, low-momenta collective oscillations of an excitonpolariton condensate in a round "box" trap. The oscillations are dominated by the dipole a…
