Thermalization of locally perturbed many-body quantum systems
Lennart Dabelow, Patrick Vorndamme, Peter Reimann
Deriving conditions under which a macroscopic system thermalizes directly from the underlying quantum many-body dynamics of its microscopic constituents is a long-standing challeng…
Observation of phase synchronization and alignment during free induction decay of quantum spins with Heisenberg interactions
P. Vorndamme, H. -J. Schmidt, Chr. Schröder +1
Equilibration of observables in closed quantum systems that are described by a unitary time evolution is a meanwhile well-established phenomenon apart from a few equally well-estab…
Theoretical formation of carbon nanomembranes under realistic conditions using classical molecular dynamics
J. Ehrens, F. Gayk, P. Vorndamme +6
Carbon nanomembranes made from aromatic precursor molecules are free standing nanometer thin materials of macroscopic lateral dimensions. Although produced in various versions for…
Modification of quantum many-body relaxation by perturbations exhibiting a banded matrix structure
Lennart Dabelow, Patrick Vorndamme, Peter Reimann
We investigate how the observable relaxation behavior of an isolated quantum many-body system is modified in response to weak-to-moderate perturbations within a nonperturbative typ…
Decoherence of a singlet-triplet superposition state under dipolar interactions of an uncorrelated environment
P. Vorndamme, J. Schnack
Recently it was shown that by means of an STM it is experimentally possible to stimulate clock transitions between the singlet and the non-magnetic triplet state of a Heisenberg-co…
Young's moduli of carbon materials investigated by various classical molecular dynamics schemes
F. Gayk, J. Ehrens, T. Heitmann +3
Classical carbon potentials together with classical molecular dynamics are employed to calculate structures and physical properties of such carbon-based materials where quantum mec…
