Fluctuation-Dissipation Relation for a Bose-Einstein Condensate of Photons
(2023-01-20)
For equilibrium systems, the magnitude of thermal fluctuations is closely linked to the dissipative response to external perturbations. This fluctuation-dissipation relation has been described for material particles in a ...
Spectroscopic Gas Sensor Based on a Fiber Fabry-Perot Cavity
(2022-10-17)
Optical spectroscopic sensors are powerful tools for analyzing gas mixtures in industrial and scientific applications. Whilst highly sensitive spectrometers tend to have a large footprint, miniaturized optical devices ...
