Open Quantum Theory of Magnetoresistance

Published:Dec 31, 2025 03:24
1 min read
ArXiv

Analysis

This paper presents a microscopic theory of magnetoresistance (MR) in magnetic materials, addressing a complex many-body open-quantum problem. It uses a novel open-quantum-system framework to solve the Liouville-von Neumann equation, providing a deeper understanding of MR by connecting it to spin decoherence and magnetic order parameters. This is significant because it offers a theoretical foundation for interpreting and designing experiments on magnetic materials, potentially leading to advancements in spintronics and related fields.
Reference

“The resistance associated with spin decoherence is governed by the order parameters of magnetic materials, such as the magnetization in ferromagnets and the Néel vector in antiferromagnets.”

Spin Physics in Real Materials: Apparent and Hidden Effects

Published:Dec 31, 2025 03:05
1 min read
ArXiv

Analysis

This paper explores spin-related phenomena in real materials, differentiating between observable ('apparent') and concealed ('hidden') spin effects. It provides a classification based on symmetries and interactions, discusses electric tunability, and highlights the importance of correctly identifying symmetries for understanding these effects. The focus on real materials and the potential for systematic discovery makes this research significant for materials science.
Reference

“The paper classifies spin effects into four categories with each having two subtypes; representative materials are pointed out.”

Ligand Shift Impact on Heisenberg Exchange and Spin Dynamics

Published:Dec 26, 2025 18:34
1 min read
ArXiv

Analysis

This paper explores a refinement to the understanding of the Heisenberg exchange interaction, a fundamental force in magnetism. It proposes that the position of nonmagnetic ions (ligands) between magnetic ions can influence the symmetric Heisenberg exchange, leading to new terms in the energy density and impacting spin wave behavior. This has implications for understanding and modeling magnetic materials, particularly antiferromagnets and ferrimagnets, and could be relevant for spintronics applications.
Reference

“The paper suggests that the ligand shift can give contribution in the constant of the symmetric Heisenberg interaction in antiferromagnetic or ferrimagnetic materials.”
