Abstract

We explore the dynamics of the simplest worm algorithm for a class of two-dimensional dimer models and argue that the dynamics of the worm head represents an example of fractional Brownian motion whenever dimer correlations in equilibrium have power-law character. Numerical estimates of the corresponding Hurst exponent and persistence exponent are obtained, and it is further argued that the Hurst exponent is completely determined by equilibrium dimer correlations, while the persistence exponent is additionally influenced by equilibrium correlations between test monomers.
