Dynamical development of long-range spatial coherence in non-equilibrium bosonic condensation
Bianca Rae Fabricante, Dąbrówka Biegańska, Paolo Comaron +14
Development of spontaneous coherence is one of the hallmarks of bosonic condensation in a variety of physical systems, such as cold atoms, confined photons, and hybrid light-matter…
Anomalous dispersion via dissipative coupling in a quantum well exciton-polariton microcavity
Dąbrówka Biegańska, Maciej Pieczarka, Christian Schneider +3
Although energy level repulsion is typically observed in interacting quantum systems, non-Hermitian physics predicts the effect of level attraction, which occurs when significant e…
Optical properties and dynamics of direct and spatially and momentum indirect excitons in AlGaAs/AlAs quantum wells
Dąbrówka Biegańska, Maciej Pieczarka, Krzysztof Ryczko +5
We present an experimental study on optical properties and dynamics of direct and spatially and momentum indirect excitons in AlGaAs/AlAs quantum wells near the crossover between $…
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…
