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…
Superradiance in dense atomic samples
I. M. de Araújo, H. Sanchez, L. F. Alves da Silva +1
Here we present an approach to the problem of superradiance in dense atomic samples, when dipolar interactions arise between atoms. Our treatment consists of the sequential use of…
Spontaneous symmetry breaking for nonautonomous pseudo-Hermitian systems
L. F. Alves da Silva, M. H. Y. Moussa
Here we first present an alternative formulation of the Lewis & Riesenfeld theorem for solving the Schrödinger equation with nonautonomous Hermitian and pseudo-Hermitian Hamiltonia…
Coherent deflection of atomic samples and positional mesoscopic superpositions
L. F. Alves da Silva, L. M. R. Rocha, M. H. Y. Moussa
We present a protocol based on the interplay between superradiance and superabsorption to achieve the coherent deflection of an atomic sample due to the momentum transfer from the…
Dynamical Casimir effect for a massless scalar field between two concentric spherical shells
F. Pascoal, L. C. Céleri, S. S. Mizrahi +1
In this work we consider the dynamical Casimir effect for a massless scalar field -- under Dirichlet boundary conditions -- between two concentric spherical shells. We obtain a gen…
