Time-dependent metric for the two dimensional, non-Hermitian coupled oscillator
Andreas Fring, Thomas Frith
We provide a time-dependent Dyson map and metric for the two dimensional harmonic oscillator with a non-Hermitian coupling term. This particular time-independent model exhib…

Time-dependent Darboux (supersymmetric) transformations for non-Hermitian quantum systems
Julia Cen, Andreas Fring, Thomas Frith
We propose time-dependent Darboux (supersymmetric) transformations that provide a scheme for the calculation of explicitly time-dependent solvable non-Hermitian partner Hamiltonian…

Quasi-exactly solvable quantum systems with explicitly time-dependent Hamiltonians
Andreas Fring, Thomas Frith
For a large class of time-dependent non-Hermitain Hamiltonians expressed in terms linear and bilinear combinations of the generators for an Euclidean Lie-algebra respecting differe…
