Wang-Landau/Multibondic Cluster Simulations for Second-Order Phase Transitions
Bernd A. Berg, Wolfhard Janke
For a second-order phase transition the critical energy range of interest is larger than the energy range covered by a canonical Monte Carlo simulation at the critical temperature.…
Residual Entropy of Ordinary Ice from Multicanonical Simulations
Bernd A. Berg, Chizuru Muguruma, Yuko Okamoto
We introduce two simple models with nearest neighbor interactions on 3D hexagonal lattices. Each model allows one to calculate the residual entropy of ice I (ordinary ice) by means…
Non-Perturbative U(1) Gauge Theory at Finite Temperature
Bernd A. Berg, Alexei Bazavov
For compact U(1) lattice gauge theory (LGT) we have performed a finite size scaling analysis on lattices for fixed by extrapolating spatial volumes of size $N_s\l…
Glauber dynamics of phase transitions: SU(3) lattice gauge theory
Alexei Bazavov, Bernd A. Berg, Alexander Velytsky
Motivated by questions about the QCD deconfining phase transition, we studied in two previous papers Model A (Glauber) dynamics of 2D and 3D Potts models, focusing on structure fac…
