Quantum phase-space representation for curved configuration spaces
Clemens Gneiting, Timo Fischer, Klaus Hornberger
We extend the Wigner-Weyl-Moyal phase-space formulation of quantum mechanics to general curved configuration spaces. The underlying phase space is based on the chosen coordinates o…
Wigner function for the orientation state
Timo Fischer, Clemens Gneiting, Klaus Hornberger
We introduce a quantum phase space representation for the orientation state of extended quantum objects, using the Euler angles and their conjugate momenta as phase space coordinat…
Membrane lateral structure: The influence of immobilized particles on domain size
Timo Fischer, H. Jelger Risselada, Richard L. C. Vink
In experiments on model membranes, a formation of large domains of different lipid composition is readily observed. However, no such phase separation is observed in the membranes o…
Domain formation in membranes with quenched protein obstacles: Lateral heterogeneity and the connection to universality classes
T. Fischer, R. L. C. Vink
We show that lateral fluidity in membranes containing quenched protein obstacles belongs to the universality class of the two-dimensional random-field Ising model. The main feature…
Fluids with quenched disorder: Scaling of the free energy barrier near critical points
T. Fischer, R. L. C. Vink
In the context of Monte Carlo simulations, the analysis of the probability distribution of the order parameter , as obtained in simulation boxes of finite linear extens…
Truncation errors in self-similar continuous unitary transformations
Nils A. Drescher, Tim Fischer, Götz S. Uhrig
Effects of truncation in self-similar continuous unitary transformations (S-CUT) are estimated rigorously. We find a formal description via an inhomogeneous flow equation. In this…
