Anomalous localization and transport behavior of amplifying periodic-on-average random systems at critical disorder
Optical amplification in a disordered system leads to modification of the localization
properties and the relative fluctuations of transport parameters. Here, we study the effect of …

Quantum echo route towards exceptional points in Anderson localized lasers
K Joshi, S Mujumdar - arXiv preprint arXiv:2301.06532, 2023 - arxiv.org
Exceptional points, that are spectral degeneracies in the parameter space of non-Hermitian
systems, have evoked a massive interest in the optical domain owing to their striking …
