Bell operator and Gaussian squeezed states in noncommutative quantum mechanics
Catarina Bastos, Alex E. Bernardini, Orfeu Bertolami +2
One examines putative corrections to the Bell operator due to the noncommutativity in the phase-space. Starting from a Gaussian squeezed envelop whose time evolution is driven by c…
Entanglement of Dirac bi-spinor states driven by Poincaré classes of $\mbox{SU}(2) \otimes \mbox{SU}(2)$ coupling potentials
Victor A. S. V. Bittencourt, Alex E. Bernardini
A generalized description of entanglement and quantum correlation properties constraining internal degrees of freedom of Dirac(-like) structures driven by arbitrary Poincaré classe…
Gaussian fidelity distorted by external fields
Jonas F. G. Santos, Alex E. Bernardini
Gaussian state decoherence aspects due to interacting magnetic-like and gravitational fields are quantified through the quantum fidelity and Shannon entropy in the scope of the pha…
bi-spinor structure entanglement induced by a step potential barrier scattering in two-dimensions
Victor A. S. V. Bittencourt, Salomon S. Mizrahi, Alex E. Bernardini
The entanglement between internal degrees of freedom of parity and helicity for reflected and transmitted waves of Dirac-like particles scattered by a potenti…
Coherent quantum squeezing due to the phase space noncommutativity
Alex E. Bernardini, Salomon S. Mizrahi
The effect of phase space general noncommutativity on producing deformed coherent squeezed states is examined. A two-dimensional noncommutative quantum system supported by a deform…
