Patterns of Genuine Multipartite Entanglement in Frustrated Quantum Spin Systems

TL;DR

This paper studies how genuine multipartite entanglement varies in different frustrated quantum spin systems, revealing that high frustration correlates with near-maximal entanglement, while low frustration systems show less consistent behavior.

Contribution

It provides a comparative analysis of multipartite entanglement across six quantum spin models with varying frustration levels, highlighting the relationship between frustration and entanglement.

Findings

Highly frustrated systems are near-maximally entangled.

Low frustration systems show inconsistent entanglement behavior.

Frustration level influences multipartite entanglement in quantum spins.

Abstract

We investigate the behavior of genuine multipartite entanglement of paradigmatic frustrated quantum spin systems. We consider six different spin models, whose frustration ranges from being very high to very low. We find that the highly frustrated quantum spin systems are near-maximally genuine multipartite entangled, while those with low frustration do not possess a similar definite behavior with regard to their genuine multipartite entanglement.
