Contribution

It introduces a minimal driven liquid model linking energy dissipation to structural and transport changes, advancing understanding of non-equilibrium materials.

Findings

Work done by non-conservative forces alters phase transitions.

Energy dissipation influences transport properties.

Time reversal symmetry violation correlates with structural modifications.

Abstract

Minimal models of active and driven particles have recently been used to elucidate many properties non-equilibrium systems. However, the relation between energy consumption and changes in the structure and transport properties of these non-equilibrium materials remains to be explored. We explore this relation in a minimal model of a driven liquid that settles into a time periodic steady state. Using concepts from stochastic thermodynamics and liquid state theories, we show how the work performed on the system by the various non-conservative, time dependent forces - this quantifies a violation of time reversal symmetry - modifies the structural, transport, and phase transition properties of the driven liquid
