sidebands, including the first-, second-, and third-order sidebands, at microwave …

Revisiting the Siegert relation for the partially coherent regime of nanolasers

M Drechsler, F Lohof, C Gies - Applied Physics Letters, 2022 - pubs.aip.org
The Siegert relation connects the first-and second-order coherence properties of light.
Although strictly valid only in the thermal regime and in the absence of correlations, this …

Stochastic resonance of spinor condensates in optical cavity

ZC Li, B Fan, L Zhou, W Zhang - Science China Physics, Mechanics & …, 2024 - Springer
Stochastic resonance is a phenomenon in which adding random noise to a system
enhances the detection or transmission of a weak signal. It occurs when the noise interacts …

Effective control and switching of optical multistability in a three-level V-type atomic system

AHM Abdelaziz, AK Sarma - Physical Review A, 2020 - APS
