Transition from diffusive to ballistic dynamics for a class of finite quantum models
Robin Steinigeweg, Heinz-Peter Breuer, Jochen Gemmer
The transport of excitation probabilities amongst weakly coupled subunits is investigated for a class of finite quantum systems. It is demonstrated that the dynamical behavior of t…

Symplectic integrators for classical spin systems
Robin Steinigeweg, Heinz-Jürgen Schmidt
We suggest a numerical integration procedure for solving the equations of motion of certain classical spin systems which preserves the underlying symplectic structure of the phase…
