Infinite series of time-dependent Dyson maps

Andreas Fring, Rebecca Tenney

We propose and explore a scheme that leads to an infinite series of time- dependent Dyson maps which associate different Hermitian Hamiltonians to a uniquely specified time-depende…

Exactly solvable time-dependent non-Hermitian quantum systems from point transformations

Andreas Fring, Rebecca Tenney

We demonstrate that complex point transformations can be used to construct non-Hermitian first integrals, time-dependent Dyson maps and metric operators for non-Hermitian quantum s…

Perturbative approach for strong and weakly coupled time-dependent non-Hermitian quantum systems

Andreas Fring, Rebecca Tenney

We propose a perturbative approach to determine the time-dependent Dyson map and the metric operator associated with time-dependent non-Hermitian Hamiltonians. We apply the method…

Spectrally equivalent time-dependent double wells and unstable anharmonic oscillators

Andreas Fring, Rebecca Tenney

We construct a time-dependent double well potential as an exact spectral equivalent to the explicitly time-dependent negative quartic oscillator with a time-dependent mass term. De…

Time-independent approximations for time-dependent optical potentials

Andreas Fring, Rebecca Tenney

We explore the possibility of modifying the Lewis-Riesenfeld method of invariants developed originally to find exact solutions for time-dependent quantum mechanical systems for the…
