Exact solutions of n-level systems and gauge theories
Merced Montesinos, Abdel Pérez-Lorenzana
We find a relationship between unitary transformations of the dynamics of quantum systems with time-dependent Hamiltonians and gauge theories. In particular, we show that the nonre…

Factorization, ladder operators and isospectral structures
A. Pérez-Lorenzana
Using the modified factorization method employed by Mielnik for the harmonic oscillator, we show that isospectral structures associated with a second order operator , can always…
