Parameter estimation in an anisotropic expanding spacetime
O. P. de Sá Neto, I. G. da Paz, P. R. S. Carvalho +1
In this work, we investigate how the anisotropy affects the cosmological parameters estimation. Here the anisotropy is incorporated as a small gravitational disturbance. We calcula…
Gouy phase of type-I SPDC-generated biphotons
F. C. V. de Brito, I. G. da Paz, Brigitte Hiller +2
We consider a double Gaussian approximation to describe the wavefunction of twin photons (also called a biphoton) created in a nonlinear crystal via a type-I spontaneous parametric…
Measuring a QED cross section via a witness particle
Jonas B. Araujo, B. Hiller, I. G. da Paz +2
We consider a QED scattering (), in which is initially entangled with a third particle () that does not participate directly in the scattering. The effect…
Fractional Angular Momenta, Gouy and Berry phases in Relativistic Bateman-Hillion-Gaussian Beams of Electrons
Robert J. Ducharme, Irismar Gonçalves da Paz, Armen G. Hayrapetyan
A new Bateman-Hillion solution to the Dirac equation for a relativistic Gaussian electron beam taking explicit account of the -position of the beam waist is presented. This solu…
Exotic looped trajectories via quantum marking
J. G. G. de Oliveira, Gustavo de Souza, L. A. Cabral +2
We provide an analytical and theoretical study of exotic looped trajectories (ELTs) in a double-slit interferometer with quantum marking. We use an excited Rydberg-like atom and wh…
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…
