The Solid-on-Solid Surface Width Around the Roughening Transition

H. G. Evertz, M. Hasenbusch, M. Marcu +1

We investigate the surface width $W$ of solid-on-solid surfaces in the vicinity of the roughening temperature $T_{r}$ . Above $T_{r}$ , $W^{2}$ is expected to diverge with the system size…

Vertex Models and Quantum Spin Systems: a nonlocal approach

H. G. Evertz, M. Marcu

Within a general cluster framework, we discuss the loop-algorithm, a new type of cluster algorithm that reduces critical slowing down in vertex models and in quantum spin systems.…
