This paper proposes and theoretically validates the nonlinear magnetoelectric Edelstein effect, a novel mechanism that generates intrinsic spin magnetization in -invariant non-centrosymmetric insulators via interplaying magnetic and electric fields, while also offering an extrinsic route for detecting Néel vector reversal in antiferromagnetic materials.
This study investigates the spin current symmetries in GdFeCo ferrimagnets across the magnetisation compensation temperature, revealing that spin Hall and spin anomalous Hall effect torques retain their signs due to distinct origins in Gd 5d and FeCo 3d electronic subsystems, respectively.
This study demonstrates coherent micrometer-range spin-wave transport in a hybrid artificial spin ice system by leveraging exchange-mediated coupling and evanescent tunneling to overcome the limitations of weak dipolar interactions, thereby enabling the investigation of spin-wave phenomena in frustrated magnetic lattices for potential analog signal processing applications.
Using a large- renormalization group approach, this paper demonstrates that three-dimensional generalized Weyl semimetals with monopole charge exhibit an anisotropic marginal non-Fermi liquid phase driven by amplified Coulomb interactions, characterized by intrinsically anisotropic screening and power-law quasiparticle suppression, in contrast to the isotropic behavior found in systems with .
This study demonstrates that hydrothermally grown chiral tellurium nanowires exhibit phase-coherent quasi-ballistic transport, gate-tunable quantum dot formation, and highly anisotropic g-factors, establishing them as a versatile platform for spin qubits and Majorana zero mode research.
This paper demonstrates that the transconductance of multilayer WSe field-effect transistors can serve as a direct electrical spectrometer for measuring intervalley relaxation times, offering three distinct signatures—Lorentzian frequency response, two-stage current transients, and sweep-rate-proportional hysteresis—that provide quantitative access to this parameter using standard instrumentation.
This paper reports the first observation of complete suppression of oscillator strength in fully polarized fractional quantum Hall states and identifies a depolarization law () as evidence for the existence of Minimal Fractionally Charged Skyrmions formed by bound spin-flip and quasiparticle excitations.
This study demonstrates that in phase-pure GaAs/InAs core/shell nanowires, increasing the contact separation length suppresses -periodic Aharonov-Bohm oscillations while enhancing -periodic Altshuler-Aronov-Spivak oscillations and their higher harmonics, a phenomenon confirmed by tight-binding simulations to indicate quasi-ballistic transport with distinct phase rigidity characteristics.
This paper utilizes exact calculations within Carroll-Field-Jackiw electrodynamics to demonstrate that Cherenkov radiation in anisotropic chiral matter can occur without a velocity threshold for slowly moving charges within specific frequency ranges, while also characterizing the resulting multi-cone emission patterns and validating the reliability of previous approximate methods.
This paper proposes a method to discriminate between different topological classes of many-body quantum states by expressing strange correlators as Kirkwood-Dirac quasiprobabilities, thereby establishing a quantum topology witness achievable through interferometric protocols involving sudden quench transformations.
