Computation of the Power Spectrum in Chaotic Inflation
Clara Rojas, Victor M. Villalba
The phase-integral approximation devised by Fröman and Fröman, is used for computing cosmological perturbations in the quartic chaotic inflationary model. The phase-integral formul…
Tunneling and transmission resonances of a Dirac particle by a double barrier
Victor M. Villalba, Luis Gonzalez-Arraga
We calculate the tunneling process of a Dirac particle across two square barriers separated a distance , as well as the scattering by a double cusp barrier where the centers of…
Computation of inflationary cosmological perturbations in chaotic inflationary scenarios using the phase-integral method
Clara Rojas, Victor M. Villalba
The phase-integral approximation devised by Fröman and Fröman, is used for computing cosmological perturbations in the quadratic chaotic inflationary model. The phase-integral form…
Particle resonance in the Dirac equation in the presence of a delta interaction and a perturbative hyperbolic potential
Victor M. Villalba, Luis A. Gonzalez-Diaz
In the present article we show that the energy spectrum of the one-dimensional Dirac equation, in the presence of an attractive vectorial delta potential, exhibits a resonant behav…
Speeding up Entanglement Degradation
R. B. Mann, V. M Villalba
Entanglement between two free bosonic modes can be determined via detection of each mode by different observers and then observing the correlations between their measurements. We s…
Two electron entanglement enhancement by an inelastic scattering process
A. Lopez, V. M. Villalba, E. Medina
In order to assess inelastic effects on two fermion entanglement production, we address an exactly solvable two-particle scattering problem where the target is an excitable scatter…
