Lindblad dynamics of the damped and forced quantum harmonic oscillator: General solution
H. J. Korsch
The quantum dynamics of a damped and forced harmonic oscillator described by a Lindblad master equation is analyzed. The master equation is converted into a matrix-vector represent…
Lindblad dynamics of the damped and forced quantum harmonic oscillator
H. J. Korsch
The quantum dynamics of a damped and forced harmonic oscillator is investigated in terms of a Lindblad master equation. Elementary algebraic techniques are employed allowing for ex…
Quasiclassical analysis of Bloch oscillations in non-Hermitian tight-binding lattices
E M Graefe, H J Korsch, A Rush
Many features of Bloch oscillations in one-dimensional quantum lattices with a static force can be described by quasiclassical considerations for example by means of the accelerati…
Computations in quantum mechanics made easy
H J Korsch, K Rapedius
Convenient and simple numerical techniques for performing quantum computations based on matrix representations of Hilbert space operators are presented and illustrated by various e…
Classical-quantum correspondence in bosonic two-mode conversion systems: polynomial algebras and Kummer shapes
Eva-Maria Graefe, Hans Jürgen Korsch, Alexander Rush
Bosonic quantum conversion systems can be modeled by many-particle single-mode Hamiltonians describing a conversion of molecules of type A into molecules of type B and vice…
Classical and quantum dynamics in the (non-Hermitian) Swanson oscillator
Eva-Maria Graefe, Hans Jürgen Korsch, Alexander Rush +1
The non-Hermitian quadratic oscillator studied by Swanson is one of the popular -symmetric model systems. Here a full classical description of its dynamics is derived using rec…
