Dynamic violation of Bell's inequalities in the angular momentum representation
J. A. López-Saldívar, O. Castaños, S. Cordero +2
A parametrization of density matrices of dimensions in terms of the raising and lowering angular momentum operators is established together with an implicit connect…

Storing Quantum Information in a generalised Dicke Model via a Simple Rotation
R. López-Peña, S. Cordero, E. Nahmad-Achar +1
A method for storing quantum information is presented for -level atomic systems interacting dipolarly with a single radiation field. The method involves performing simple local…

Wigner Function Analysis of Finite Matter-Radiation Systems
E. Nahmad-Achar, R. López-Peña, S. Cordero +1
We show that the behaviour in phase space of the Wigner function associated to the electromagnetic modes carries the information of both, the entanglement properties between matter…
