Thermodynamics of O(3) Classical Heisenberg Model in Multipath Metropolis Simulation

We study the thermodynamics of classical Heisenberg model using the multipath approach to Metropolis algorithm Monte Carlo simulation. This simulation approach produces uncorrelated results with known precision. Also, it can be easily generalized to other classical models of magnetism. Comparing results obtained from multipath and from single--path simulations we demonstrate that these approaches produce equivalent results.
