Crossover phenomena in spin models with medium-range interactions and self-avoiding walks with medium-range jumps.
We study crossover phenomena in a model of self-avoiding walks with medium-range jumps, which corresponds to the limit N-->0 of an N-vector spin system with medium-range interactions. In particular, we consider the critical crossover limit that interpolates between the Gaussian and the Wilson-Fisher fixed point. The corresponding crossover functions are computed by using field-theoretical metho...
متن کاملMean-field expansion for spin models with medium-range interactions
We study the critical crossover between the Gaussian and the Wilson-Fisher fixed point for general O(N)-invariant spin models with medium-range interactions. We perform a systematic expansion around the mean-field solution, obtaining the universal crossover curves and their leading corrections. In particular we show that, in three dimensions, the leading correction scales as R−3, R being the ra...
متن کاملMedium-range interactions and crossover to classical critical behavior.
We study the crossover from Ising-like to classical critical behavior as a function of the range R of interactions. The power-law dependence on R of several critical amplitudes is calculated from renormalization theory. The results confirm the predictions of Mon and Binder, which were obtained from phenomenological scaling arguments. In addition, we calculate the range dependence of several cor...
متن کاملRole of medium-range interactions in proteins.
The energies of oligopeptide segments of lysozyme are minimized with respect to the dihedral angles of the central residue. As the length of the oligopeptide segment increases, up to a nonapeptide, the low-energy conformation becomes that observed in the x-ray structure in most cases. This finding suggests that, while short-range interactions appear to play the dominant role in determining the ...
متن کاملMonte Carlo Simulation of Spin Models with Long-Range Interactions
An efficient Monte Carlo algorithm for the simulation of spin models with long-range interactions is discussed. Its central feature is that the number of operations required to flip a spin is independent of the number of interactions between this spin and the other spins in the system. In addition, critical slowing down is strongly suppressed. In order to illustrate the range of applicability o...
