Momentum-space non-Hermitian skin effect in an exciton-polariton system
Yow-Ming, Hu, Mateusz Król +11
Localization of a macroscopic number of eigenstates on a real-space boundary, known as the non-Hermitian skin effect, is one of the striking topological features emerging from non-…

Anomalous dispersion via dissipative coupling in a quantum well exciton-polariton microcavity
DÄ brówka BiegaÅska, 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
DÄ brówka BiegaÅska, 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 $…
