Efficient Diagonalization of Kicked Quantum Systems
R. Ketzmerick, K. Kruse, T. Geisel
We show that the time evolution operator of kicked quantum systems, although a full matrix of size NxN, can be diagonalized with the help of a new method based on a suitable combin…

Avoided Band Crossings: Tuning Metal-Insulator Transitions in Chaotic Systems
R. Ketzmerick, K. Kruse, T. Geisel
We show that avoided crossings of energy bands may give rise to a variety of phenomena such as transitions from metal to insulator and vice versa, changes in localization lengths,…
