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…

Microscopic model for Bose-Einstein condensation and quasiparticle decay

Tim Fischer, Sebastian Duffe, Götz S. Uhrig

Sufficiently dimerized quantum antiferromagnets display elementary S=1 excitations, triplon quasiparticles, protected by a gap at low energies. At higher energies, the triplons may…

Finite size scaling in Ising-like systems with quenched random fields: Evidence of hyperscaling violation

R. L. C. Vink, T. Fischer, K. Binder

In systems belonging to the universality class of the random field Ising model, the standard hyperscaling relation between critical exponents does not hold, but is replaced by a mo…
