Floquet Systems with Hall Effect: Topological Properties and Phase Transitions
Itzhack Dana, Kazuhiro Kubo
We study the quantum topological properties of Floquet (time-periodic) systems exhibiting Hall effects due to perpendicular magnetic and electric fields. The systems are charged pa…

Creation Mechanism of Devil's Staircase Surface and Unstable and Stable Periodic Orbit in the Anisotropic Kepler Problem
Tokuzo Shimada, Keita Sumiya, Kazuhiro Kubo
A long-standing question in two dimensional Anisotropic Kepler Problem (AKP) concerns with the uniqueness of an unstable periodic orbit (PO) for a given binary code (modulo symmetr…

Kicked Hall Systems: Quantum-Dynamical and Spectral Manifestations of Generic Superweak Chaos
Itzhack Dana, Kazuhiro Kubo
Classical "kicked Hall systems" (KHSs), i.e., periodically kicked charges in the presence of uniform magnetic and electric fields that are perpendicular to each other and to the ki…
