Influence of the field-detector coupling strength on the dynamical Casimir effect
A. S. M. de Castro, A. Cacheffo, V. V. Dodonov
We consider the problem of photon creation from vacuum inside an ideal cavity with vibrating walls in the resonance case, taking into account the interaction between the resonant f…
A Laplace transform approach to the quantum harmonic oscillator
Douglas R. M. Pimentel, Antonio S. de Castro
The one-dimensional quantum harmonic oscillator problem is examined via the Laplace transform method. The stationary states are determined by requiring definite parity and good beh…
Spin and Pseudospin symmetries in the Dirac equation with central Coulomb potentials
A. S. de Castro, P. Alberto
We analyze in detail the analytical solutions of the Dirac equation with scalar S and vector V Coulomb radial potentials near the limit of spin and pseudospin symmetries, i.e., whe…
Bound states in a double delta potential via Laplace transform
A. S. de Castro
The problem of bound states in a double delta potential is revisited by means of Laplace transform method. Quite differently from direct methods, no knowledge about the jump discon…
