Open Quantum Theory of Magnetoresistance
Analysis
Key Takeaways
- •Develops a microscopic theory of magnetoresistance within an open-quantum-system framework.
- •Connects MR to spin decoherence, including spin relaxation and dephasing.
- •Links resistance to magnetic order parameters (magnetization, Néel vector).
- •Offers a theoretical basis for understanding and designing experiments on magnetic materials.
“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.”
