Parity anomaly laser
Daria A. Smirnova, Pramod Padmanabhan, Daniel Leykam
We propose a novel supersymmetry-inspired scheme for achieving robust single mode lasing in arrays of coupled microcavities, based on factorizing a given array Hamiltonian into its…

Exceptional points in topological edge spectrum of PT symmetric domain walls
Xiang Ni, Daria Smirnova, Alexander Poddubny +3
We demonstrate that the non-Hermitian parity-time (PT) symmetric interfaces formed between amplifying and lossy crystals support dissipationless edge states. These PT edge states e…
