Emergence of thermodynamic behavior within composite quantum systems
Guenter Mahler, Jochen Gemmer, Mathias Michel
Entanglement within a given device provides a potential resource for quantum information processing. Entanglement between system and environment leads to decoherence (thus suppress…
Observation of field-dependent magnetic parameters in the magnetic molecule {Ni4Mo12}
J. Schnack, M. Brueger, M. Luban +9
We investigate the bulk magnetic, electron paramagnetic resonance, and magneto-optical properties of {Ni4Mo12}, a magnetic molecule with antiferromagnetically coupled tetrahedral {…
From Pure Schroedingerian to Statistical Dynamics
Jochen Gemmer, Mathias Michel
Many processes in nature seem to be entirely controlled by transition rates and the corresponding statistical dynamics. Some of them are in essence quantum, like the decay of excit…
Superposition in nonlinear wave and evolution equations
H. W. Schuermann, V. S. Serov, J. Nickel
Real and bounded elliptic solutions suitable for applying the Khare-Sukhatme superposition procedure are presented and used to generate superposition solutions of the generalized m…
Quantum Heat Transport: Perturbation Theory in Liouville Space
Mathias Michel, Jochen Gemmer, Guenter Mahler
We consider chains consisting of several identical subsystems weakly coupled by various types of next neighbor interactions. At both ends the chain is coupled to a respective heat…
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…
