Exotic looped trajectories in double-slit experiments with matter waves

Carlos Vieira, Helder Alexander, Gustavo de Souza +2

We study the observation of exotic looped trajectories in double-slit experiments with matter waves. We consider the relative intensity at as a function of the time-of-flight…

Nonlocal single particle correlations and EPR state in the double-slit experiment

Oziel de Araujo, Helder Alexander, Marcos Sampaio +1

Quantum correlations of observables for two particle states have demonstrated the nonlocal character of the quantum mechanics. However nonlocality can be exhibited even for noncomm…

Entanglement of self interacting scalar fields in an expanding spacetime

Helder Alexander, Gustavo de Souza, Paul Mansfield +2

We evaluate self-interaction effects on the quantum correlations of field modes of opposite momenta for scalar theory in a two-dimensional asymptotically flat Robertson-Walk…

Momentum correlations of scattered particles in quantum field theory: one-loop entanglement generation

Ricardo Faleiro, Rafael Pavão, Helder Alexander +3

We compute the entanglement entropy variation between initial (separable or entangled in the momenta) and final states in an elastic scattering of a bipartite system compose…

Entanglement between two scalar fields in an expanding spacetime

Helder Alexander, I. G. da Paz, Marcos Sampaio

We study the evolution of the two scalar fields entangled via a mutual interaction in an expanding spacetime. We compute the logarithmic negativity to leading order in perturbation…

Gouy phase in non-classical paths in triple-slit interference experiment

Irismar da Paz, Carlos Vieira, Robert Ducharme +3

We propose a simple model to study the Gouy phase effect in the triple-slit experiment in which we consider a non-classical path. The Gouy phase differs for classical or non-classi…
