Non-Hermitian dispersion sign reversal of radiative resonances in two dimensions
R. Binder, J. S. Schaibley, N. H. Kwong
In a recent publication [Wurdack et al., Nat. Comm. 14:1026 (2023)], it was shown that in microcavities containing atomically thin semiconductors non-Hermitian quantum mechanics ca…

Gapless fluctuations and exceptional points in semiconductor lasers
N. H. Kwong, M. Em. Spotnitz, R. Binder
We analyze the spectrum of spatially uniform, single-particle fluctuation modes in the linear electromagnetic response of a semiconductor laser. We show that if the decay rate of t…
