Structure and dynamics of a glass-forming binary complex plasma with non-reciprocal interaction

TL;DR

This study uses simulations to explore how non-reciprocal interactions influence the structure and glassy dynamics of a binary complex plasma, revealing that non-reciprocity significantly affects glass formation.

Contribution

First numerical investigation of a quasi-two-dimensional binary complex plasma with non-reciprocal interactions, highlighting their impact on glassy dynamics and structure.

Findings

Non-reciprocal interactions shift glass formation behavior.

The system exhibits long-time alpha-relaxation indicative of glassy dynamics.

Qualitative signatures of glass formation are similar in reciprocal and non-reciprocal cases.

Abstract

In this letter, we present the first numerical study on the structural and dynamical properties of a quasi-two-dimensional (q2D) binary complex plasma with Langevin dynamics simulation. The effect of interaction with non-reciprocity on the structure is investigated by comparing systems with pure Yukawa and with point-wake Yukawa interactions. The long-time alpha-relaxation for the latter system is revealed by plotting and analyzing the intermediate scattering function. The results clearly indicate that a q2D binary complex plasma is a suitable model system to study the dynamics of a glass former. The non-reciprocity of the interactions shifts the glass formation significantly but leads to the same qualitative signatures as in the reciprocal case.
