Distribution of the spacing between two adjacent avoided crossings
Manabu Machida, Keiji Saito
We consider the frequency at which avoided crossings appear in an energy level structure when an external field is applied to a quantum chaotic system. The distribution of the spac…

Landau-Zener transitions in qubits controlled by electromagnetic fields
Martijn Wubs, Keiji Saito, Sigmund Kohler +2
We investigate the influence of a dipole interaction with a classical radiation field on a qubit during a continuous change of a control parameter. In particular, we explore the no…

Spectral Form Factor for Chaotic Dynamics in a Weak Magnetic Field
Keiji Saito, Taro Nagao
Using semiclassical periodic orbit theory for a chaotic system in a weak magnetic field, we obtain the form factor predicted by Pandey and Mehta's two matrix model up to the third…
