A Fabry-Perot interferometer with quantum mirrors: nonlinear light transport and rectification
F. Fratini, E. Mascarenhas, L. Safari +5
Optical transport represents a natural route towards fast communications, and it is currently used in large scale data transfer. The progressive miniaturization of devices for info…
Spin effects probed by Rayleigh X-ray scattering off hydrogenic ions
Laleh Safari, Jose Paulo Santos, Pedro Amaro +1
We study the polarization characteristics of x-ray photons scattered by hydrogenic atoms, based on the Dirac equation and second-order perturbation theory. The relativistic states…
Angular and polarization analysis for two-photon decay of 2s hyperfine states of hydrogenlike Uranium
Laleh Safari, Pedro Amaro, Jose Paulo Santos +1
The amplitude of two-photon transitions between hyperfine states in hydrogenlike ions is derived based on relativistic Dirac equation and second order perturbation theory. We study…
Quantum mechanical evolution operator in the presence of a scalar linear potential: discussion on the evolved state
Filippo Fratini, Laleh Safari
We discuss the form of the wave-function of a state subjected to a scalar linear potential, paying special attention to quantum tunneling. We analyze the phases acquired by the evo…
