Collective Mpemba-Type Relaxation in Degenerate Bosonic Modes Coupled to a Common Thermal Reservoir
I. M. de Araújo, H. Sanchez, L. F. Alves da Silva +2
We investigate collective Mpemba-type relaxation in a degenerate family of bosonic modes coupled to a common thermal reservoir. Starting from a fully symmetric M-mode description a…

From superradiance to collective EIT in three-level ensembles
Hugo Sanchez, Luis F. A. da Silva, Mickel A. Ponte +2
We investigate the collective dynamics of a three-level ensemble under the Dicke limit, revealing a unified connection between superradiant emission and electromagnetically induced…

Superradiance and Superabsorption Engine of Two-Level Systems: -Power Scaling at Near-Unity Efficiency
L. F. Alves da Silva, H. Sanchez, M. A. Ponte +2
We present a thermal engine that exploits the \emph{cooperative superradiance} and \emph{superabsorption} of a sample of \(N\) two-level atoms. This engine operates using a single…
