The freezing R\`enyi quantum discord

TL;DR

This paper investigates the freezing phenomenon of R`enyi quantum discord in a two-dimer system coupled to correlated environments, demonstrating its persistence under non-Markovian conditions and analyzing parameter effects.

Contribution

It is the first study to analyze the freezing behavior of R`enyi quantum discord in a non-Markovian two-dimer system with correlated environments.

Findings

Freezing of R`enyi discord persists under non-Markovian dynamics.

Parameter variations influence the freezing behavior.

Freezing phenomena are consistent with quantum discord properties.

Abstract

As a universal quantum character of quantum correlation, the freezing phenomenon is researched by geometry and quantum discord methods, respectively. In this paper, the properties of R`enyi discord is studied for two independent Dimer System coupled to two correlated Fermi-spin environments under the non-Markovian condition. We further demonstrate that the freezing behaviors still exist for R`enyi discord and study the effects of different parameters on this behaviors.
