The effect of quantum fluctuations on a nearly flat, nonrelativistic two-dimensional membrane with extrinsic curvature stiffness and tension is investigated. The renormalization group analysis is...
Test of variational approximation for +4 quantum chain (1994)
Monte Carlo Simulation, Wolfhard Janke A, Tilman Sauer B, Communicated A. Lagendijk
We report results of a Monte Carlo simulation of the @4 quantum chain. In order to enhance the efficiency of the simulation we combine muItig~d simulation techniques with a refined discretization...
