ArXiv

Analysis

This article presents a research paper on a specific area of condensed matter physics. The focus is on understanding and modeling the phenomenon of negative magnetoresistance in a particular class of materials called multi-Weyl semimetals. The use of a 'quantum framework' suggests a theoretical or computational approach to the problem. The source, ArXiv, indicates that this is a pre-print or a submitted paper, not necessarily peer-reviewed yet.

    Unconventional Superconductivity in MoTe2 Studied with Kinetic Inductance

    Published:Dec 31, 2025 06:53
    1 min read
    ArXiv

    Analysis

    This paper investigates the pairing symmetry of the unconventional superconductor MoTe2, a Weyl semimetal, using a novel technique based on microwave resonators to measure kinetic inductance. This approach offers higher precision than traditional methods for determining the London penetration depth, allowing for the observation of power-law temperature dependence and the anomalous nonlinear Meissner effect, both indicative of nodal superconductivity. The study addresses conflicting results from previous measurements and provides strong evidence for the presence of nodal points in the superconducting gap.
    Reference

    “The high precision of this technique allows us to observe power-law temperature dependence of $λ$, and to measure the anomalous nonlinear Meissner effect -- the current dependence of $λ$ arising from nodal quasiparticles. Together, these measurements provide smoking gun signatures of nodal superconductivity.”

    High-Performance, Polarization-Independent Nonreciprocal Thermal Emitters

    Published:Dec 30, 2025 18:33
    1 min read
    ArXiv

    Analysis

    This paper addresses the challenge of creating highly efficient, pattern-free thermal emitters that are nonreciprocal (emission properties depend on direction) and polarization-independent. This is important for advanced energy harvesting and thermal management technologies. The authors propose a novel approach using multilayer heterostructures of magneto-optical and magnetic Weyl semimetal materials, avoiding the limitations of existing metamaterial-based solutions. The use of Pareto optimization to tune design parameters is a key aspect for maximizing performance.
    Reference

    “The findings show that omnidirectional polarization-independent nonreciprocity can be achieved utilizing multilayer structures with different magnetization directions that do not follow simple vector summation.”

    ArXiv

    Analysis

    This paper introduces a novel mechanism for realizing altermagnetic Weyl semimetals, a new type of material with unique topological properties. The authors explore how an altermagnetic mass term can drive transitions between different Chern phases, leading to the creation of helical Fermi arcs. This work is significant because it expands our understanding of Dirac systems and provides a pathway for experimental realization of these materials.
    Reference

    “The paper highlights the creation of coexisting helical Fermi arcs with opposite chirality on the same surface, a phenomenon not found in conventional magnetic Weyl semimetals.”

    Tunable Magnetic and Topological Phases in EuMnXBi2 Pnictides

    Published:Dec 26, 2025 10:53
    1 min read
    ArXiv

    Analysis

    This paper investigates the electronic, magnetic, and topological properties of layered pnictides EuMnXBi2 (X = Mn, Fe, Co, Zn) using density functional theory (DFT). It highlights the potential of these materials, particularly the Bi-based compounds, for exploring tunable magnetic and topological phases. The study demonstrates how spin-orbit coupling, chemical substitution, and electron correlations can be used to engineer these phases, opening avenues for exploring a wide range of electronic and magnetic phenomena.
    Reference

    “EuMn2Bi2 stabilizes in a C-type antiferromagnetic ground state with a narrow-gap semiconducting character. Inclusion of spin-orbit coupling (SOC) drives a transition from this trivial antiferromagnetic semiconductor to a Weyl semimetal hosting four symmetry-related Weyl points and robust Fermi arc states.”
