Monte Carlo Determination of the Low-Energy Constants of a Spin 1/2 Heisenberg Model with Spatial Anisotropy
F. J. Jiang, F. Kämpfer, M. Nyfeler
Motivated by the possible mechanism for the pinning of the electronic liquid crystal direction in YBCO as proposed in \cite{Pardini08}, we use the first principles Monte Carlo meth…
Constraint Effective Potential of the Staggered Magnetization in an Antiferromagnet
U. Gerber, C. P. Hofmann, F. -J. Jiang +2
We employ an improved estimator to calculate the constraint effective potential of the staggered magnetization in the spin quantum Heisenberg model using a loop-clus…
Loop-Cluster Simulation of the - Model on the Honeycomb Lattice
F. -J. Jiang, F. Kämpfer, M. Nyfeler +1
Inspired by the lattice structure of the unhydrated variant of the superconducting material NaCoOyHO at , we study the - model on a honeycomb la…
Nested Cluster Algorithm for Frustrated Quantum Antiferromagnets
M. Nyfeler, F. -J. Jiang, F. Kämpfer +1
Simulations of frustrated quantum antiferromagnets suffer from a severe sign problem. We solve the ergodicity problem of the loop-cluster algorithm in a natural way and apply a pow…
From an Antiferromagnet to a Valence Bond Solid: Evidence for a First Order Phase Transition
F. -J. Jiang, M. Nyfeler, S. Chandrasekharan +1
Using a loop-cluster algorithm we investigate the spin 1/2 Heisenberg antiferromagnet on a square lattice with exchange coupling and an additional four-spin interaction of stre…
A new efficient Cluster Algorithm for the Ising Model
Matthias Nyfeler, Michele Pepe, Uwe-Jens Wiese
Using D-theory we construct a new efficient cluster algorithm for the Ising model. The construction is very different from the standard Swendsen-Wang algorithm and related to worm…
