Phase transitions in systems with aggregation and shattering

2017-10-17T10:00:00+00:00

Author(s): P. L. Krapivsky, W. Otieno, and N. V. Brilliantov

This paper presents a model of aggregation in which collisions between the particles and clusters can lead to shattering of the clusters with a certain probability. The authors obtain the phase diagram of this process, observe a phase transition depending on the shattering probability, and show how, in one of the regimes, the initial conditions of the system crucially affect its evolution.

Stochastic maps, continuous approximation, and stable distribution

2017-10-17T10:00:00+00:00

Author(s): David A. Kessler and Stanislav Burov

A continuous approximation framework for general nonlinear stochastic as well as deterministic discrete maps is developed. For the stochastic map with uncorelated Gaussian noise, by successively applying the Itô lemma, we obtain a Langevin type of equation. Specifically, we show how nonlinear maps g...

In this work we analyze the ground-state properties of the $s=1/2$ one-dimensional axial next-nearest-neighbor Ising model in a transverse field using the quantum fidelity approach.

Noise-induced drift in two-dimensional anisotropic systems

2017-10-17T10:00:00+00:00

Author(s): Oded Farago

We study the isothermal Brownian dynamics of a particle in a system with spatially varying diffusivity. Due to the heterogeneity of the system, the particle's mean displacement does not vanish even if it does not experience any physical force. This phenomenon has been termed “noise-induced drift,” a...
