This paper introduces and theoretically establishes the intrinsic nonlinear pure spin Hall effect (NPSHE) in 39 magnetic point groups, demonstrating that materials like Kramers-Weyl metals can generate pure spin currents without charge flow to enable energy-efficient spintronic devices.
This paper demonstrates that a chain of parametrically driven quantum resonators coupled solely by weak cross-Kerr interactions can undergo a spontaneous symmetry-breaking transition into a non-trivial topological phase, where the topology is dictated by the nonlinear interaction structure rather than quadratic tunneling, resulting in distinct effective models and observable edge modes depending on boundary conditions.
This paper demonstrates that by exploiting complex noise correlations arising from interrelated shuttling paths and encoding logical qubits in pairs of consecutively shuttled entangled spins, one can significantly enhance shuttling fidelity and protect against decoherence even at slow speeds.
This study demonstrates that chiral ionic gating enables handedness-dependent electric-field control of two-dimensional ferromagnetism in FeSi(111) thin films by biasing magnetic domain populations through chirality-induced symmetry breaking, offering a novel strategy for chiral spintronics.
This paper demonstrates that nitrogen-vacancy (NV) centers in diamond can serve as local quantum sensors to detect the unique momentum-space anisotropy and spin-polarized bands of altermagnetic insulators, thereby distinguishing them from conventional antiferromagnets through orientation-dependent relaxation measurements.
This paper demonstrates that spatially varying linearly polarized light can dynamically generate and control pseudo-magnetic fields in three-dimensional Weyl semimetals via Floquet engineering, offering a reversible and non-invasive alternative to strain-induced gauge fields with distinct experimental signatures in optical and transport properties.
This paper reports the observation of gate-tunable Josephson diode effects in adjacent magic-angle twisted bilayer graphene junctions, demonstrating that microscopic inhomogeneities drive non-uniform supercurrent distributions that enable the efficient tuning and polarity reversal of nonreciprocal supercurrents.
This paper demonstrates that on a lattice with proper regularization and translational symmetry, massive Dirac fermions exhibit integer-quantized Hall conductivity rather than the half-quantized response associated with the parity anomaly, which is shown to be a property exclusive to massless Dirac fermions.
This paper establishes a general macroscopic formalism to distinguish between Hall and Rashba-Edelstein contributions to spin- and orbital-to-charge conversion in noncentrosymmetric materials, demonstrating through a case study of ferroelectric GeTe that the Rashba-Edelstein effect is the dominant mechanism driving charge current generation.
This paper demonstrates that multi-site mesoscopic quantum Hall circuits with four or more sites exhibit interaction-driven non-Fermi liquid physics and unique quantum-critical points due to higher-order backscattering processes, establishing them as a versatile platform for simulating quantum critical phenomena that can be experimentally controlled and restored to a boundary sine-Gordon description via multichannel channel looping.
