Decoupled Cell Method Monte Carlo Simulation for Quantum Spin Systems
Shigeo Homma, H. Matsuda, N. Ogita
The internal energy and perpendicular susceptibility of the one-dimentional XY-model are calculated by the decoupled cell method Monte Carlo simulation for quantum systems. Above a cenrain demarcation temperature depending on the cell size the agreement with the exact result is excellent, whereas below it the result of simulation becomes unreliable.
