Three PT-symmetric Hamiltonians with completely different spectra
Francisco M. Fernández, Javier Garcia
We discuss three Hamiltonians, each with a central-field part and a PT-symmetric perturbation . When is the isotropic Harmonic oscillator the spectrum is real…

Highly accurate calculation of the resonances in the Stark effect in hydrogen
Francisco M Fernández, Javier Garcia
We obtained accurate resonances for the Stark effect in hydrogen by means of three independent methods. Two of them are based on complex rotation of the coordinates and diagonaliza…

On recent calculations of resonances for the Stark effect in hydrogen
Francisco M. Fernández, Javier Garcia
We show that the resonances of the Stark effect in hydrogen reported in Phys. Rev. A \textbf{88}, 022509 (2013) are considerably less accurate than the number of digits appear to s…
