In the first part I discuss some aspects of the use of Monte Carlo algorithms to generate the raw data. Collective Monte Carlo Updating for Spin Systems. One of these algorithms generalizes readily to other frustrated systems, such as Ising antiferromagnets on the Kagome lattice with further neighbour couplings. We demonstrate its efficiency in the two-dimensional O(n) σ models for n=1 (Ising) and n=2 (x−y) at their critical temperatures, and for n=3 (Heisenberg) with correlation lengths around 10 and 20. 15 pages. Site will undergo maintenance and will not be available from 11:00 PM EST on 22 August, 2020 until 01:00 AM EST on 23 August, 2020. On lattices up to 1282 no sign of critical slowing down is visible with autocorrelation times of 1-2 steps per spin for estimators of long-range quantities. Yang Z, Haijun Z, Zhong-Can OY.

We demonstrate its efficiency in the two-dimensional O(n) σ models for n=1 (Ising) and n=2 (x−y) at their critical temperatures, and for n=3 (Heisenberg) with correlation lengths around 10 and 20. Physical Description: We demonstrate its efficiency in the two-dimensional O(n) σ models for n=1 (Ising) and n=2 (x−y) at their critical temperatures, and for n=3 (Heisenberg) with correlation lengths around 10 and 20.

The aim is to generate a representative ensemble of configurations to access thermodynamical quantities without the need to solve the system analytically or to perform an exact enumeration. for e cient and ergodic Monte Carlo simulations of frustrated Ising models with arbitrary two-spin interactions that extend up to third-neighbours on the triangular lattice. A Monte Carlo algorithm is presented that updates large clusters of spins simultaneously in systems at and near criticality. Spin glass problems have been successfully studied on FPGA base systems by Belletti et al. See Off-Campus Access to Physical Review for further instructions.
