Reset Induced Multimodality in Unbounded Potential

Abstract

Resetting, as a protocol that restarts the evolution of a system, can significantly influence stochastic dynamics. One notable effect is the emergence of stationary states in unbounded potentials, where such states would otherwise be absent without resetting. In this work, we explore unbounded potentials for which resetting not only induces stationary states but also leads to their multimodality, despite the repulsive nature of the potential. We present examples of potentials that, despite lacking local minima, can generate trimodal and pentamodal states, and we investigate how the modal structure of these states varies with noise intensity and resetting frequency.
