On the two-dimensional harmonic oscillator with an electric field confined to a circular box
Francisco M. Fernández, Javier Garcia, Norberto Aquino +1
We revisit the quantum-mechanical two-dimensional harmonic oscillator with an electric field confined to a circular box of impenetrable walls. In order to obtain the energy spectru…
On the eigenvalues of the harmonic oscillator with a Gaussian perturbation
Paolo Amore, Francisco M. Fernández, Javier Garcia
We test the analytical expressions for the first two eigenvalues of the harmonic oscillator with a Gaussian perturbation proposed recently. Our numerical eigenvalues show that thos…
On the variational treatment of a class of double-well oscillators
Francisco M. Fernández, Javier Garcia
We compare the well known Rayleigh-Ritz variational method (RRVM) with a recently proposed approach based on supersymmetric quantum mechanics and the Gram-Schmidt orthogonalization…
Dirac equation in exotic spacetimes
Javier Faba García, Carlos Sabín
We find solutions of the Dirac equation in curved spacetime. In particular, we consider 1+1 dimensional sections of several exotic metrics: the Alcubierre metric, which describes a…
