Time-dependent quantum harmonic oscillator: a continuous route from adiabatic to sudden changes
D. Martínez-Tibaduiza, L. Pires, C. Farina
In this work, we provide an answer to the question: how sudden or adiabatic is a change in the frequency of a quantum harmonic oscillator (HO)? To do this, we investigate the behav…

New BCH-like relations of the su(1, 1), su(2) and so(2, 1) Lie algebras
D. M. Tibaduiza, A. H. Aragão, C. Farina +1
In this work we demonstrate new BCH-like relations involving the generators of the su(1, 1), su(2) and so(2, 1) Lie algebras. We use our results to obtain in a straightforward way…
