    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.”

    Quantum Spin Liquids in Cuprates: Resolving Discrepancies

    Published:Dec 30, 2025 03:26
    1 min read
    ArXiv

    Analysis

    This paper addresses the challenges faced by quantum spin liquid theories in explaining the behavior of hole-doped cuprate materials, specifically the pseudogap metal and d-wave superconductor phases. It highlights the discrepancies between early theories and experimental observations like angle-dependent magnetoresistance and anisotropic quasiparticle velocities. The paper proposes the Fractionalized Fermi Liquid (FL*) state as a solution, offering a framework to reconcile theoretical models with experimental data. It's significant because it attempts to bridge the gap between theoretical models and experimental realities in a complex area of condensed matter physics.
    Reference

    “The paper reviews how the fractionalized Fermi Liquid (FL*) state, which dopes quantum spin liquids with gauge-neutral electron-like quasiparticles, resolves both difficulties.”
