Sorkin parameter for type-I spontaneous parametric down-conversion biphotons and matter waves
F. C. V. de Brito, C. H. S. Vieira, I. G. da Paz +2
We propose experimental measurements of the logarithmic negativity, which quantifies quantum correlations using Gouy phase measurements in an asymmetric double-slit interference ex…
Interacting fermions in an expanding spacetime
L. N. Machado, H. A. S. Costa, I. G. da Paz +2
We evaluate the effect of quantum electrodynamics on the correlations between Dirac field modes corresponding electron-positron pairs of opposite momenta generated by expansion of…
Parameter estimation for a Lorentz invariance violation
H. A. S. Costa, P. R. S. Carvalho, I. G. da Paz
We employ techniques from quantum estimation theory (QET) to estimate the Lorentz violation parameters in the 1+3-dimensional flat spacetime. We obtain and discuss the expression o…
