Aging following a zero-temperature quench in the Ising model
Denis Gessert, Henrik Christiansen, Wolfhard Janke
Aging in phase-ordering kinetics of the Ising model following a quench from infinite to zero temperature is studied by means of Monte Carlo simulations. In this model the two…
Optimal Energy Estimation in Path-Integral Monte Carlo Simulations
Wolfhard Janke, Tilman Sauer
We investigate the properties of two standard energy estimators used in path-integral Monte Carlo simulations. By disentangling the variance of the estimators and their autocorrela…
Resummation of anisotropic quartic oscillator. Crossover from anisotropic to isotropic large-order behavior
H. Kleinert, S. Thoms
We present an approximative calculation of the ground-state energy for the anisotropic anharmonic oscillator Using an instanton solution of the isotropic action , we obtain t…
Convergence behavior of variational perturbation expansion-- A method for locating Bender-Wu singularities
H. Kleinert, W. Janke
Variational perturbation expansions have recently been used to calculate directly the strong-coupling expansion coefficients of the anharmonic oscillator. The convergence is expone…
Multibondic Cluster Algorithm for Monte Carlo Simulations of First-Order Phase Transitions
Wolfhard Janke, Stefan Kappler
Inspired by the multicanonical approach to simulations of first-order phase transitions we propose for -state Potts models a combination of cluster updates with reweighting of t…
Multicanonical multigrid Monte Carlo method and effective autocorellation time
W. Janke, T. Sauer
We report tests of the recently proposed multicanonical multigrid Monte Carlo method for the two-dimensional field theory. Defining an effective autocorrelation time we obtai…
Scaling in Steiner Random Surfaces
C. F. Baillie, A. Irback, W. Janke +1
It has been suggested that the modified Steiner action functional has desirable properties for a random surface action. In this paper we investigate the scaling of the string tensi…
Ising Model Universality for Two-Dimensional Lattices
W. Janke, M. Katoot, R. Villanova
We use the single-cluster Monte Carlo update algorithm to simulate the Ising model on two-dimensional Poissonian random lattices of Delaunay type with up to 80\,000 sites. By apply…
Multicanonical Multigrid Monte Carlo
W. Janke, T. Sauer
To further improve the performance of Monte Carlo simulations of first-order phase transitions we propose to combine the multicanonical approach with multigrid techniques. We repor…
Critical Exponents of the Classical 3D Heisenberg Model: A Single-Cluster Monte Carlo Study
Christian Holm, Wolfhard Janke
We have simulated the three-dimensional Heisenberg model on simple cubic lattices, using the single-cluster Monte Carlo update algorithm. The expected pronounced reduction of criti…
