Wigner`s quantum phase-space current in weakly-anharmonic weakly-excited two-state systems
Dimitris Kakofengitis, Ole Steuernagel
There are no phase-space trajectories for anharmonic quantum systems, but Wigner's phase-space representation of quantum mechanics features Wigner current~. This current rev…

The Quantum Liouville Equation is non-Liouvillian
Dimitris Kakofengitis, Ole Steuernagel
The Hamiltonian flow of a classical, time-independent, conservative system is incompressible, it is Liouvillian. The analog of Hamilton's equations of motion for a quantum-mechanic…

Equivalence between free quantum particles and those in harmonic potentials and its application to instantaneous changes
Ole Steuernagel
In quantum physics the free particle and the harmonically trapped particle are arguably the most important systems a physicist needs to know about. It is little known that, mathema…
