From free-evolution to tomographic representation
Sergio Cordero, Ramón López-Peña, Eduardo Nahmad-Achar +3
We use the free evolution propagator to determine the quantum probability representation (i.e., the general expression of the tomogram) of any one-dimensional system described by a…

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…

Quantum Phase Diagrams of Matter-Field Hamiltonians II: Wigner Function Analysis
Ramón López-Peña, Sergio Cordero, Eduardo Nahmad-Achar +1
Non-classical states are of practical interest in quantum computing and quantum metrology. These states can be detected through their Wigner function negativity in some regions. In…
