This study demonstrates that while orbital currents from light metals (Mn, Ti) can transfer angular momentum to a ferrimagnetic Gd-Fe-Co alloy, they fail to drive domain wall motion due to weak torque conversion and insufficient interfacial stabilization, a limitation that is overcome only by inserting a thin platinum layer to facilitate orbital-to-spin conversion.
This paper demonstrates that an external bias magnetic field can tune the oscillation frequency and reverse the sign of the nonlinearity coefficient in a confined cylindrical skyrmion oscillator, offering a pathway to develop tunable computational elements for neuromorphic applications.
ANT:UI is a Python-based interactive 3D graphical interface that automates the construction and preparation of molecular junction geometries for NEGF-DFT quantum transport calculations, significantly streamlining the workflow for generating ready-to-run Gaussian and ANT.Gaussian input files through intuitive point-and-click tools.
This paper demonstrates that combining magnetic flux, quasiperiodicity, and engineered asymmetric electrode-coupling geometry in Su-Schrieffer-Heeger rings can dramatically enhance the thermoelectric figure of merit to approximately 90 by optimizing quantum interference and energy filtering while violating the Wiedemann-Franz law.
This paper introduces a transparency-engineered rf-SQUID cell design that utilizes asymmetric series junctions and flux bias to independently control the potential expansion, enabling operating points where the detrimental Kerr nonlinearity is suppressed while preserving the cubic nonlinearity required for three-wave-mixing Josephson metamaterials and traveling-wave parametric amplifiers.
This paper demonstrates that embedding a quantum point contact within an edge-magnetoplasmon resonator allows for the unambiguous detection of integer and fractional quantum Hall states through radiofrequency transmission, while electrostatic gating enables the precise characterization of edge magnetoplasmon paths and the validation of a geometric model for the system.
This paper establishes the quantitative validity and limitations of modeling two series-connected Josephson junctions as a single synthetic high-transparency element under finite-frequency drive, demonstrating that the reduced single-degree-of-freedom description remains accurate at low frequencies but deviates significantly as the drive frequency approaches the plasma-frequency scale.
This paper reports a deterministic single-photon source that achieves an in-fibre single-photon flux exceeding 500 MHz with over 100 pW of optical power by combining high excitation rates with high system efficiency.
Using low-temperature scanning tunneling microscopy, this study reveals that individual Sm adatoms on graphene/Ir(111) exhibit reversible variable charge states, distinct magnetic excitations confirming a Sm ground state with retained 4f filling, and a novel Kondo resonance with a large Zeeman splitting.
This paper presents a direct electrical detection method for spin chemical potential generated by the Spin Hall Effect in -Tungsten and Platinum using a ferromagnetic-normal metal voltage probe pair, which successfully validates the measurement scheme through reciprocity with the Inverse Spin Hall Effect and reveals a pronounced power-law dependence of spin Hall resistivity on material resistivity across a wide range.
