Comment on ``Wigner phase space description of a Morse oscillator''
Wigner's representation of quantum mechanics in integral form and its applications
Dimitris Kakofengitis, Maxime Oliva, Ole Steuernagel
We consider quantum phase-space dynamics using Wigner's representation of quantum mechanics. We stress the usefulness of the integral form for the description of Wigner's phase-spa…
Anharmonic quantum mechanical systems do not feature phase space trajectories
Maxime Oliva, Dimitris Kakofengitis, Ole Steuernagel
Phase space dynamics in classical mechanics is described by transport along trajectories. Anharmonic quantum mechanical systems do not allow for a trajectory-based description of t…
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…
Wigner flow reveals topological order in quantum phase space dynamics
Ole Steuernagel, Dimitris Kakofengitis, Georg Ritter
The behaviour of classical mechanical systems is characterised by their phase portraits, the collections of their trajectories. Heisenberg's uncertainty principle precludes the exi…
