Superradiance and Superabsorption Engine of $N$ Two-Level Systems: $N^2$-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…
