This paper proposes a chip-scale, room-temperature nitrogen-vacancy magnetometer that utilizes a passive magnonic cavity formed by a defect in a YIG/CoFeB magnonic crystal to enhance sensitivity, projecting a best-case performance of 19 pT/ by optimizing NV-magnon coupling and spin linewidth.
This paper investigates one-dimensional spin chains with a continuous exponential symmetry , revealing that the interplay between spin magnitude and the exponential base dictates distinct topological behaviors, including a novel "half-SPT" phase with a single protected edge mode for half-odd integer spins and even , thereby uncovering new symmetry-protected gapped phases beyond existing classification schemes.
This study demonstrates that strong out-of-plane displacement fields induce the ionization of intrinsic defect states within high-quality hexagonal boron nitride (hBN), causing significant charge transfer and carrier inhomogeneity in encapsulated graphene, thereby challenging the assumption that hBN remains electronically inert in van der Waals heterostructures.
This paper proposes and analyzes a field-free switching scheme in perpendicular magnetic tunnel junctions where cooperative spin-orbit torque and spin-transfer torque drive ultrafast, reliable magnetization reversal by ensuring the pulse-end state is sufficiently close to the target direction to prevent back-switching, thereby establishing the pulse-end magnetization state as the decisive factor for switching performance.
This paper proposes that mastering energy band tail states, which currently limit the performance and energy efficiency of monolayer 2D semiconductors due to their rough band edges, is essential for their successful integration into low-power nanoelectronics and outlines specific strategies to mitigate these effects.
This paper proposes using electron-paramagnetic resonance (EPR) spectroscopy to distinguish between competing microscopic models of chirality-induced spin selectivity (CISS) by identifying unique spectral signatures of associated radical pair states, thereby providing a critical experimental pathway for validating theoretical mechanisms in photoinduced charge transfer.
This paper demonstrates that a charged particle moving outside a screw dislocation in a uniform magnetic field exhibits an exactly solvable radial dynamics with an equally spaced, orientation-dependent energy spectrum, where the global screw geometry couples axial and azimuthal motion to create spectral asymmetry while the magnetic field provides radial confinement.
This paper demonstrates that while a voltage-biased driven-dissipative quantum critical system is organized by an effective temperature, its steady state is selected via a non-Boltzmann rule that shifts the first-order transition away from the equal-depth point of a deterministic potential.
This paper theoretically demonstrates that driving a spin qubit in a parabolic quantum wire with a bichromatic field generates confinement-tunable non-Abelian synthetic gauge fields, enabling robust Floquet topological phenomena and fast holonomic quantum gates that surpass environmental decoherence, particularly in GaAs/AlGaAs nanowire systems.
This paper demonstrates that while parity-protected qubits can achieve millisecond relaxation times (), their coherence is fundamentally limited to microsecond-scale dephasing times () due to an unavoidable trade-off between charge and flux noise, thereby establishing practical constraints on the long-term viability of this qubit architecture.
