Lewis-Ermakov approach for the time-dependent two-level system
M. Huerta-Sandoval, I. Ramos-Prieto, H. M. Moya-Cessa
We construct an explicit Lewis-Ermakov-type dynamical invariant for time-dependent two-level systems by exploiting their algebraic correspondence with the time-dependent harmonic o…

The Dirac sea of phase: Unifying phase paradoxes and Talbot revivals in multimode waveguides
N. Korneev, I. Ramos-Prieto, H. M. Moya-Cessa
The quantum mechanical description of phase remains a fundamental challenge, with theoretical efforts tracing from the early works of London and Dirac to discrete formalisms. In th…
