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…

Non-Hermitian noncommutative quantum mechanics
Jonas F. G. Santos, Fabricio. S. Luiz, Oscar. S. Duarte +1
In this work we present a general formalism to treat non-Hermitian and noncommutative Hamiltonians. This is done employing the phase-space formalism of quantum mechanics, which all…

Proposal to produce long-lived mesoscopic superpositions through an atom-driven field interaction
C. J. Villas-Boas, F. R. de Paula, R. M. Serra +1
We present a proposal for the production of longer-lived mesoscopic superpositions which relies on two requirements: parametric amplification and squeezed vacuum reservoir for cavi…
