Simulating spin measurement with a finite heat bath model for the environment
Thomas Dittrich, Óscar Rodrí guez, Carlos Viviescas
Spin measurement is studied as a unitary time evolution of the spin coupled to an environment representing the meter and the apparatus. Modelling the environment as a heat bath com…
Classical and quantum chaotic angular-momentum pumps
T. Dittrich, F. L. Dubeibe
We study directed transport of charge and intrinsic angular momentum by periodically driven scattering in the regime of fast and strong driving. A spin-orbit coupling through a kic…
Pumping angular momentum by driven chaotic scattering
T. Dittrich, F. L. Dubeibe
Chaotic scattering with an internal degree of freedom and the possibility to generate directed transport of angular momentum is studied in a specific model, a magnetic dipole movin…
Classical and Quantum Hamiltonian Ratchets
Holger Schanz, Marc-Felix Otto, Roland Ketzmerick +1
We explain the mechanism leading to directed chaotic transport in Hamiltonian systems with spatial and temporal periodicity. We show that a mixed phase space comprising both regula…
