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…
Solvable two dimensional time-dependent non-Hermitian quantum systems with infinite dimensional Hilbert space in the broken PT-regime
Andreas Fring, Thomas Frith
We provide exact analytical solutions for a two dimensional explicitly time-dependent non-Hermitian quantum system. While the time-independent variant of the model studied is in th…
A squeezed review on coherent states and nonclassicality for non-Hermitian systems with minimal length
Sanjib Dey, Andreas Fring, Véronique Hussin
It was at the dawn of the historical developments of quantum mechanics when Schrödinger, Kennard and Darwin proposed an interesting type of Gaussian wave packets, which do not spre…
