Diffusion coefficients of fluctuations in semi-infinite ferromagnets
2014 The nearest-neighbour Ising model of a semi-infinite ferromagnet in which nearsurface couplings may differ from their bulk values is considered. In the critical region near secondorder phase transitions the decay of fluctuations of the magnetization density is described by a diffusion equation with a damping term. Using mean-field theory, the diffusion coefficients of fluctuations in the p...

متن کاملOne-Dimensional Diffusion in a Semi-Infinite Poisson Random Force
We consider the one-dimensional diffusion of a particle on a semiinfinite line and in a piecewise linear random potential. We first present a new formalism which yields an analytical expression for the Green function of the Fokker-Planck equation, valid for any deterministic construction of the potential profile. The force is then taken to be an asymmetric dichotomic process. Solving the corres...
متن کاملDiffusion of noninteracting particles into a semi-infinite lattice.
Consider a gas of noninteracting particles diffusing into a semi-infinite lattice, Z+×ZD−1, subject to exclusion of double occupancy. An exact closed set of equations can be obtained and solved (in closed form) for the single-site occupancies or densities. Equations for the n-site occupancies couple only to such functions for n and n-1 sites, as for an infinite lattice. Their analysis reveals t...
متن کاملDiffraction coefficients of a semi-infinite planar crack embedded in a transversely-isotropic space
We have considered a semi-infinite crack embedded in a transversely isotropic medium and studied two special cases, one, in which the axis of symmetry is normal to the crack face and the wave incidence is arbitrary and another, in which the axis lies in the crack plane normal to the edge and the incident wave vector is also normal to the edge. The problem is of interest in Non-Destructive Evalu...
