Perturbation theory for short-range weakly-attractive potentials in one dimension
Paolo Amore, Francisco M. Fernández
We have obtained the perturbative expressions up to sixth order for the energy of the bound state in a one dimensional, arbitrarily weak, short range finite well, applying a method…
Local Quantum Thermometry using Unruh-De Witt detectors
Sandra Robles, Javier Rodriguez-Laguna
We propose an operational definition for the local temperature of a quantum field employing Unruh-DeWitt detectors, as used in the study of the Unruh and Hawking effects. With this…
On two different kinds of resonances in one-dimensional quantum-mechanical models
Francisco M. Fernández, Javier Garcia
We apply the Riccati-Padé method and the Rayleigh-Ritz method with complex rotation to the study of the resonances of a one-dimensional well with two barriers. The model exhibits t…
On the construction of pseudo-Hermitian Hamiltonians by means of similarity transformations
Francisco M. Fernández
We generalize a recently proposed approach for the construction of pseudo-Hermitian Hamiltonians with real spectra. Present technique is based on a simple and straightforward simil…
Improved power-series method for confined one-dimensional quantum-mechanical problems
Francisco M. Fernández
We propose two improvements to the well-known power series method for confined one-dimensional quantum-mechanical problems. They consist of the addition of a variational step were…
