Suppression of selection among broken-symmetry states by cross-correlated noises in double-well system

TL;DR

This paper investigates how cross-correlated white noises influence state selection in a double-well system, revealing a re-entrant symmetry transition driven by noise intensities.

Contribution

It demonstrates the suppression of state selection due to correlated noises and uncovers a re-entrant symmetry transition as noise parameters vary.

Findings

Suppression of state selection by correlated noises.

Re-entrant symmetry transition as a function of additive noise.

Impact of noise correlation on system symmetry.

Abstract

Suppression of selection among broken-symmetry states has been found in double-well system resulting from two simultaneous correlated white noises, one additive and the other multiplicative. Symmetry-asymmetry-symmetry transition is re-entrant as a function of the additive noise intensity for small multiplicative noise.
