Directed Paths on Hierarchical Lattices with Random Sign Weights
We study sums of directed paths on a hierarchical lattice where each bond has either a positive or negative sign with a probability p. Such path sums J have been used to model interference effects by hopping electrons in the strongly localized regime. The advantage of hierarchical lattices is that they include path crossings, ignored by mean field approaches, while still permitting analytical t...
متن کاملLectures on Directed Paths in Random Media
Many physical problems involve calculating sums over paths. Each path could represent one possible physical realization of an object such as a polymer, in which case the weight of the path is the probability of that configuration. The weights themselves could be imaginary as in the case of Feynman paths describing the amplitude for the propagation of a particle. Path integral calculations are n...
متن کاملRandom walks with sign reversals and the intrinsic angular momentum behaviour on lattices
2014 Classical uniaxial rotators on lattices are considered. The assumption is made that the rotators exchange angular momentum only in a certain sector of relative orientations (collision sector) because of the finite range of the anisotropic interaction potential; the latter may in particular be a hard core potential (instantaneous collisions). Since the axes of the rotators are supposed to b...
متن کاملCovering partially directed graphs with directed paths
We consider graphs which contain both directed and undirected edges (partially directed graphs). We show that the problem of covering the edges of such graphs with a minimum number of edge-disjoint directed paths respecting the orientations of the directed edges is polynomially solvable.We exhibit a good characterization for this problem in the form of a min–max theorem.We introduce a more gene...
متن کاملWeights of Continuous Lattices
The papers [25], [20], [1], [9], [12], [10], [22], [3], [15], [2], [23], [19], [26], [24], [27], [21], [8], [18], [5], [11], [6], [17], [16], [4], [14], and [7] provide the terminology and notation for this paper. In this article we present several logical schemes. The scheme UparrowUnion deals with a relational structure A and a unary predicate P, and states that: Let S be a family of subsets ...
