Gouy Phase across PT-Symmetry Breaking in Non-Hermitian Dirac Systems
Dirlan J. C. de Morais Sousa, Lucas S. Marinho, Giandomenico Palumbo +1
We study relativistic beam-like wave packets governed by a quasi-Hermitian massive Dirac Hamiltonian and uncover anomalous Gouy-phase behavior in non-Hermitian dynamics. We show th…
Matter-Wave Squeezing from Gouy Phase: Toward a New Tool for Quantum Technology
Thiago M. S. Oliveira, Lucas S. Marinho, F. C. V. de Brito +2
We investigate the Gouy phase emerging from the time evolution of confined matter waves in a harmonic potential. Specifically, we analyze the quantum dynamics of a Gaussian wavepac…
Temperature and non-Markovian parameter estimation in quantum Brownian motion
João C. P. Porto, Carlos H. S. Vieira, Irismar G. da Paz +2
We investigate a quantum metrological protocol operating in a non-Markovian environment by employing the quantum Brownian motion (QBM) model, in which the system is linearly couple…
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…
