Statistics of reduced words in locally free and braid groups: Abstract studies and application to ballistic growth model

Jean Desbois 1, Sergei K. Nechaev 1, 2 Journal of Physics A 31 (1998) 2767-2784 We study numerically and analytically the average length of reduced (primitive) words in so-called locally free and braid groups. We consider the situations when the letters in the initial words are drawn either without or with correlations. In the latter case we show that the average …

Scaling universalities of kth-nearest neighbor distances on closed manifolds

A. G. Percus 1, O. C. Martin 2 Advances in Applied Mathematics 21 (1998) 424-436 Take N sites distributed randomly and uniformly on a smooth closed surface. We express the expected distance from an arbitrary point on the surface to its kth-nearest neighboring site, in terms of the function A(l) giving the area of a disc of radius l …

Rough droplet model for spherical metal clusters

N. Pavloff 1, C. Schmit 1 Physical Review B 58 (1998) 4942-4951 We study the thermally activated oscillations, or capillary waves, of a neutral metal cluster within the liquid drop model. These deformations correspond to a surface roughness which we characterize by a single parameter $\\Delta$. We derive a simple analytic approximate expression determining $\\Delta$ as a function of …

Random Walks, Reaction-Diffusion, and Nonequilibrium Dynamics of Spin Chains in One-dimensional Random Environments

Daniel Fisher 1, Pierre Le Doussal 2, Cecile Monthus 3 Physical Review Letters 80 (1998) 3539-3542 Sinai\’s model of diffusion in one-dimension with random local bias is studied by a real space renormalization group which yields asymptotically exact long time results. The distribution of the position of a particle and the probability of it not returning to the origin are obtained, …

Random Operator Approach for Word Enumeration in Braid Groups

Alain Comtet 1, Sergei K. Nechaev 1, 2 Journal of Physics A 31 (1998) 5609-5630 We investigate analytically the problem of enumeration of nonequivalent primitive words in the braid group B_n for n >> 1 by analysing the random word statistics and the target space on the basis of the locally free group approximation. We develop a \’symbolic dynamics\’ method for …

Quantum liquids of particles with generalized statistics

Serguei B. Isakov 1, 2 Physics Letters A 242 (1998) 130-138 We propose a phenomenological approach to quantum liquids of particles obeying generalized statistics of a fermionic type, in the spirit of the Landau Fermi liquid theory. The approach is developed for fractional exclusion statistics. We discuss both equilibrium (specific heat, compressibility, and Pauli spin susceptibility) and nonequilibrium …
