Chiral oscillations in the non-relativistic regime
Victor A. S. V. Bittencourt, Alex E. Bernardini, Massimo Blasone
Massive Dirac particles are a superposition of left and right chiral components. Since chirality is not a conserved quantity, the free Dirac Hamiltonian evolution induces chiral qu…
Classical and statistical limits of the quantum singular oscillator
Caio Fernando e Silva, Alex E. Bernardini
The classical boundaries of the quantum singular oscillator (SO) is addressed under Weyl-Wigner phase-space and Bohmian mechanics frameworks as to comparatively evaluate phase-spac…
Phase-space elementary information content of confined Dirac spinors
Alex E. Bernardini
Reporting about the Wigner formalism for describing Dirac spinor structures through a covariant phase-space formulation, the quantum information quantifiers for purity and mutual i…
On the elementary information content of thermodynamic ensembles
Alex E. Bernardini
Extending the definition of phase-space (Wigner) quantum projectors to thermodynamic ensembles usually results into an efficient platform for quantifying their elementary informati…
Lorentz Invariant Quantum Concurrence for SU(2) x SU(2) spin-parity states
Alex E. Bernardini, Victor A. S. V. Bittencourt, Massimo Blasone
The quantum concurrence of spin-parity states is shown to be invariant under Lorentz boosts and rotations when the density matrices are const…
Anharmonic effects on phase-space quantum profiles: an exact approach
Alex E. Bernardini, Caio Fernando e Silva
Given its well known spectral decomposition profile, the -dim harmonic oscillator potential modified by an inverse square (-dim angular momentum-like) contribution works as a…
