TL;DR

This paper investigates a new type of irreversible phase transitions triggered by oscillatory inputs, revealing second order transitions with scale invariance belonging to directed percolation universality, and contrasting behaviors for first order transitions.

Contribution

It introduces a novel class of IPTs driven by oscillatory inputs and characterizes their critical properties and universality classes through computer simulations.

Findings

Second order IPTs exhibit scale invariance.

Second order IPTs belong to directed percolation universality class.

First order IPTs show no universality.

Abstract

A novel kind of irreversible phase transitions (IPT's) driven by an oscillatory input parameter is studied by means of computer simulations. Second order IPT's showing scale invariance in relevant dynamic critical properties are found to belong to the universality class of directed percolation. In contrast, the absence of universality is observed for first order IPT's.
