Dynamics of self-organized driven particles with competing range interaction

TL;DR

This paper investigates how particles with competing interactions self-organize into dynamic patterns under external driving forces, revealing various phases including disordered, depinned, and stripe formations depending on system parameters.

Contribution

It introduces a comprehensive dynamical phase diagram for driven particles with competing interactions, highlighting the formation of stripe patterns in different directions based on pinning strength.

Findings

Dynamic patterns evolve with increasing drive

Stripe formations depend on pinning strength

A phase diagram summarizes the pattern regimes

Abstract

Non-equilibrium self-organized patterns formed by particles interacting through competing range interaction are driven over a substrate by an external force. We show that, with increasing driving force, the pre-existed static patterns evolve into dynamic patterns either via disordered phase or depinned patterns, or via the formation of non-equilibrium stripes. Strikingly, the stripes are formed either in the direction of the driving force or in the transverse direction, depending on the pinning strength. The revealed dynamical patterns are summarized in a dynamical phase diagram.
