Long-lived triggering optical superradiance in doped Van Vleck paramagnetics

, 2020
The theory of long-lived optical triggering optical superradiance is developed by the method of non-equilibrium statistical Zubarev-Peletminsky operator.

Analytical and numerical studies of periodic superradiance

We conduct a theoretical study to understand the periodic superradiance observed in an Er:YSO crystal. First, we construct a model based on the Maxwell-Bloch equations for a reduced level system, a pair of superradiance states and a population reservoir ...

Effects of Superradiance in Active Galactic Nuclei

International audienceA spinning supermassive black hole (SMBH) at the core of an active galactic nucleus (AGN) provides room for the elusive ultra-light scalar particles (ULSP) to be produced through a phenomenon called \textit{superradiance}.

Numerical simulation of Dicke superradiance in a semiconductor laser device

, 2011
This paper reports a theoretical model for Dicke Superradiance in semiconductor laser devices. Simulations agree well with previously-observed superradiance properties and are used to optimize driving conditions and device ...
