Local resetting with geometric confinement

نویسندگان

چکیده

"Local resetting" was recently introduced to describe stochastic resetting in interacting systems where particles independently try reset a common "origin". Our understanding of such systems, the process is itself affected by interactions, still very limited. One ubiquitous constraint that often imposed on dynamics geometric confinement, e.g. restricting rigid spherical channel so narrow overtaking becomes difficult. We here explore interplay between local and confinement system consisting two species diffusive particles: "bath" particles, "tracers" which undergo resetting. Mean-field analysis numerical simulations show tracers, whose stationary density profile exhibits typical "tent-like" shape, imprint this shape onto bath profile. Upon varying ratio degree over particle diffusivity, found transition states. In one tracers expel away from origin, while other they ensnare them instead. Between these states, we find special case mean field approximation exact.

A Geometric Realization of Confinement

We study the geometric realization of the Higgs phenomenon in type II string compactifications on Calabi–Yau manifolds. The string description is most directly phrased in terms of confinement of magnetic flux, with magnetic charged states arising from D-branes wrapped around chains as opposed to cycles. The rest of the closed cycle of the D-brane worldvolume is manifested as a confining flux tu...

Geometric Approach to Quark Confinement

Interactions that explain quark confinement correspond, in the first approximation, to interactions in 2-D space-time. In this paper, we show that this fact has a geometric explanation: Namely, • on the most fundamental geometric level (of causality relations) quark confinement means that causality forms a lattice (i.e., an ordering in which every two events have the least upper bound and the g...

Tropical Geometric Interpretation of Ultradiscrete Singularity Confinement

We present a new interpretation of the ultradiscretization procedure in terms of a non-archimedean valuation on the field of Puiseux series. We shall demonstrate how the new interpretation of the ultradiscretization gives a correspondence between singularity confinement for discrete mappings and ultradiscrete singularity confinement for ultradiscrete mappings using results from tropical geometr...

Compressive sensing with local geometric features Citation

We propose a framework for compressive sensing of images with local geometric features. Specifically, let x ∈ R be an N -pixel image, where each pixel p has value xp. The image is acquired by computing the measurement vector Ax, where A is an m×N measurement matrix for some m N . The goal is then to design the matrix A and recovery algorithm which, given Ax, returns an approximation to x. In th...

Contour Tree Simplification With Local Geometric Measures

The contour tree, an abstraction of a scalar field that encodes the nesting relationships of isosurfaces, has several potential applications in scientific and medical visualization, but noise in experimentally-acquired data results in unmanageably large trees. We attach geometric properties of the contours to the branches of the tree and apply simplification by persistence to reduce the size of...
