3D classical and quantum stable structures of dissipative systems
arXiv:1809.01716 · doi:10.1103/PhysRevE.99.012214
Abstract
We study the properties of classical and quantum stable structures in a 3D parameter space corresponding to the dissipative kicked top. This is a model system in quantum and classical chaos that gives a starting point for many body examples. We are able to identify the influence of these structures in the spectra and eigenstates of the corresponding (super)operators. This provides with a complementary view with respect to the typical 2D parameter space systems found in the literature. Many properties of the eigenstates, like its localization behaviour can be generalized to this higher dimensional parameter space and spherical phase space topology. Moreover we find a 3D phenomenon -- generalizable to more dimensions -- that we call the coalescence-separation of (q)ISSs, whose main consequence is a marked enhancement of quantum localization. This could be of relevance for systems which have attracted a lot of attention very recently.
