This paper demonstrates that smooth spatial variations of the Néel order in altermagnets act as emergent gauge fields to induce strong, tunable in-plane anisotropies in electrical conductivity and linear dichroism, providing direct optical and transport probes for spin-textured states without requiring intrinsic spin-orbit coupling.
This paper theoretically predicts that the Dzyaloshinskii-Moriya interaction induces a magnon equilibrium spin current in collinear antiferromagnets—an effect analogous to superconducting supercurrents that is large enough to be experimentally observable via magnon interference in a ring geometry under an external electric field.
This paper develops a symmetry-adapted multipolar theory for noncentrosymmetric crystals in the strong spin-orbit coupling limit, revealing that multipolar interactions for reshape Fermi surfaces and create distinct total-angular-momentum textures that lead to nonmonotonic, enhanced Edelstein effects in heavy-element materials.
This paper demonstrates that within the Unified Nonequilibrium Perturbative framework, the anyonic exchange phase in Fractional Quantum Hall edges is fundamentally tied to Luttinger liquid scaling dimensions, yielding unique solutions for both Poissonian and super-Poissonian DC backscattering currents and noise through a derived nonequilibrium fluctuation-dissipation relation.
This paper proposes robust protocols using spatially local anyon injection at a single quantum point contact to isolate the universal anyonic statistical phase from nonuniversal interaction effects, deriving novel fluctuation-dissipation relations that allow for the direct experimental measurement of this phase via AC admittance or DC noise.
This paper proposes using microwave absorption visibility in cavity-coupled nanowires as a robust probe to distinguish nonlocal Majorana bound states from trivial zero-energy modes, based on the distinct requirement that true Majoranas only yield finite visibility when both ends are simultaneously coupled to the cavity.
This paper theoretically demonstrates that a non-zero magnon thermal Hall effect can occur in collinear antiferromagnets at zero external magnetic field, driven by symmetry-breaking mechanisms such as sublattice asymmetry in compensated Néel order or Dzyaloshinskii-Moriya interactions in weak ferromagnets, and proposes a model where an external electric field can modulate this effect by altering the system's symmetry.
This paper reports the experimental realization and characterization of an individual V2+ ion embedded in a CdTe/ZnTe quantum dot, where polarization-resolved magneto-photoluminescence combined with numerical modeling confirms the system's properties and identifies its fundamental spin-1/2 state as a promising localized qubit.
By combining scanning tunneling microscopy, critical scaling analysis, and magnetocaloric measurements, this study demonstrates that structural layering in MnBiTe compounds fundamentally governs their magnetic critical fluctuations and magnetocaloric responses, with MnBiTe exhibiting robust 3D Ising-like criticality and dual-type magnetocaloric effects, while MnBiTe displays crossover-dominated criticality and conventional magnetocaloric behavior due to weakened interlayer exchange.
This paper demonstrates that atomic force nanolithography can precisely engineer tunable in-plane uniaxial magnetic anisotropy in permalloy films by creating nanoscale groove arrays, enabling controlled domain manipulation for applications in magnonic elements and anisotropic magnetoresistance sensors.
This paper establishes a general framework for intrinsic nonlinear thermal conductivity in bosonic systems using a quantum kinetic equation approach that naturally incorporates energy magnetization, identifying quantum-geometric contributions like thermal Berry-connection polarizability (TBCP) that dominate nonlinear thermal Hall effects and differ quantitatively from semiclassical predictions.
This paper theoretically demonstrates that mass asymmetry between two interacting Brownian particles induces a net directional information flow from the heavier to the lighter particle, driven by the heavier particle's superior inertia and memory capacity, with the transfer magnitude scaling logarithmically with the mass ratio.
This paper presents a computationally efficient microscopic screening theory for excitons in two-dimensional materials that bridges the gap between effective models and first-principles methods by employing an atomistic description with quantum-screened interactions to accurately estimate binding energies and address discrepancies in existing literature.
This study employs self-consistent Hartree-Fock calculations to demonstrate that proximity-induced spin-orbit coupling from a transition-metal dichalcogenide layer critically tunes the spin nature and symmetry-breaking patterns of correlated ground states in twisted mono-bilayer graphene, driving transitions between various magnetic orders and inducing chiral non-coplanar states depending on the specific type and combination of Rashba and Ising coupling.
This paper introduces a gauge transformation that eliminates time-dependent onsite potentials by renormalizing hopping terms with phase factors, thereby simplifying time-ordered integrals and facilitating the simulation of pulse propagation in scattering systems.
This paper introduces an analytical parabolic-cylinder approach to model valley-polarized conductance in tilted anisotropic Dirac-Weyl systems, revealing how distinct tilt components govern tunneling and resonance behaviors to identify robust operating conditions for materials like 8-Pmmn borophene and WTe2.
This paper introduces topological heavy-tailed networks by constructing a tight-binding model for the Apollonian network with nontrivial gauge fields to reveal the "Apollonian butterfly" spectrum, demonstrating how spectral localizers characterize its topological features as being governed by lower-degree nodes and bridging topological physics with network science for wave control.
This paper identifies extrinsic population dynamics as the fundamental cause of discrepancies between theoretical and experimental lifetime estimates in multilevel systems, proposing a revised readout protocol and an integrated theory that successfully explains recent spin-valley measurements in bilayer graphene.
This study demonstrates that in gated InAs/GaSb bilayers, Coulomb interactions drive a transition from a quantum spin Hall insulator to a robust excitonic topological order with spontaneous time-reversal symmetry breaking, particularly in the dilute regime or under magnetic fields where triplet electron-hole pairing emerges.
This paper presents a computationally efficient theoretical framework based on the Power-Zienau-Woolley Hamiltonian and maximally localized Wannier functions that accurately captures light-matter interactions beyond the electric-dipole approximation in extended systems without requiring finite-order multipole expansions, thereby enabling precise first-principles simulations of spatially structured light dynamics in nanoscale materials.
