Nodal domains on quantum graphs
Sven Gnutzmann, Uzy Smilansky, Joachim Weber
We consider the real eigenfunctions of the Schrödinger operator on graphs, and count their nodal domains. The number of nodal domains fluctuates within an interval whose size equal…
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…
Frobenius-Perron Resonances for Maps with a Mixed Phase Space
Joachim Weber, Fritz Haake, Petr Seba
Resonances of the time evolution (Frobenius-Perron) operator P for phase space densities have recently been shown to play a key role for the interrelations of classical, semiclassi…
