Classical versus Quantum Time Evolution of Densities at Limited Phase-Space Resolution
Christopher Manderfeld, Joachim Weber, Fritz Haake
We study the interrelations between the classical (Frobenius-Perron) and the quantum (Husimi) propagator for phase-space (quasi-)probability densities in a Hamiltonian system displ…

Resonances of the Frobenius-Perron Operator for a Hamiltonian Map with a Mixed Phase Space
Joachim Weber, Fritz Haake, Petr A. Braun +2
Resonances of the (Frobenius-Perron) evolution operator P for phase-space densities have recently attracted considerable attention, in the context of interrelations between classic…

Perturbed closed geodesics are periodic orbits: Index and Transversality
Joa Weber
We study the classical action functional $\SMC_V$ on the free loop space of a closed, finite dimensional Riemannian manifold and the symplectic action $\AMC_V$ on the free loop…
