Classical versus quantum time evolution of (quasi-) probability densities at limited phase-space resolution
We study the interrelations between the classical (Frobenius–Perron) and the quantum (Husimi) propagator for phase-space (quasi-)probability densities in a Hamiltonian system displaying a mix of regular and chaotic behaviour. We focus on common resonances of these operators which we determine by blurring phase-space resolution (Weber J et al 2000 Phys. …
