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…

Coherent transfer of topological domain walls
Paolo Comaron, Vanik Shahnazaryan, Michał Matuszewski
We demonstrate the controlled coherent transfer of topological domain walls in a one-dimensional non-Hermitian chain of interacting Bose-Einstein condensates. The topological prote…

Non-Hermitian Topological End-Mode Lasing in Polariton Systems
Paolo Comaron, Vanik Shahnazaryan, Wojciech Brzezicki +2
We predict the existence of non-Hermitian topologically protected end states in a one-dimensional exciton-polariton condensate lattice, where topological transitions are driven by…
