"The classical skeleton of open quantum chaotic maps"
L.A. Raviola, A.M.F. Rivas and G.G. Carlo
Physica D 240(22) (2011) 1818-1824
We have studied two complementary decoherence measures, purity and fidelity, for a generic diffusive noise in two different chaotic systems (the baker map and the cat map). For both quantities, we have found classical structures in quantum mechanics-the scar functions-that are specially stable when subjected to environmental perturbations. We show that these quantum states constructed on classical invariants are the most robust significant quantum distributions in generic dissipative maps.
