This paper introduces a simplified nanomechanical platform that directly detects electron vortices by measuring the torque-induced vibrations of a suspended resonator containing a circular cavity, thereby establishing nanomechanics as a powerful tool for studying electron hydrodynamics and viscosity.
This paper proposes that a vibrationally-mediated Dzyaloshinskii-Moriya interaction, driven by low-energy torsional modes modulating hopping and spin-orbit coupling in donor-acceptor molecules, serves as the predictive mechanism for Chirality-Induced Spin Selectivity, successfully explaining experimental magnetic field and temperature dependencies.
This paper proves the existence of topologically nontrivial energy-minimizing maps with higher degrees in a magnetic skyrmion model by strategically inserting truncated Belavin-Polyakov profiles into lower-degree configurations, provided the domain is sufficiently large or slender to prevent degree loss.
This paper reports that PbTe-Pb hybrid nanowires exhibit a significantly enhanced Landé g-factor of up to 83, attributed to orbital effects in the superconducting film, which lowers the critical magnetic field required for topological superconductivity.
This study demonstrates that highly hydrogenated monolayer graphene exhibits long-term stability in ultra-high vacuum but rapidly oxidizes in air, a process that can be effectively reversed through re-exposure to atomic hydrogen, highlighting its potential for hydrogen storage applications.
This study demonstrates that the ferromagnetic ground state of single-crystalline NdGaSi splits quasi-flat 4f bands near the Fermi energy, enabling localized f-electrons to directly generate a record-breaking intrinsic anomalous Hall conductivity of 1165 cm, a phenomenon absent in its non-magnetic analog NdAlSi.
This paper derives a reduced energy functional for ultrathin ferromagnetic multilayers hosting skyrmions and demonstrates that in bilayer systems, the global energy minimizers consist of two antiparallel Néel skyrmions stabilized by stray field coupling.
This paper demonstrates that quantum systems can be universally cooled without prior knowledge of their spectral details by employing randomized interactions with a reservoir of ground-state meter qubits, where resonant energy-exchange processes dominate over heating under weak coupling and long interaction times.
This paper presents an experimental approach using out-of-plane angle-resolved Second Harmonic Hall measurements and anomalous Hall effect-based spin-torque ferromagnetic resonance to quantify damping-like and field-like spin-orbit torque efficiencies in perpendicular magnetic anisotropy systems, revealing a unique magnetization-dependent anomalous field-like torque in Ta/CoFeB bilayers.
This paper demonstrates that coupling a kagome system to a circularly polarized cavity mode induces Chern insulating phases with topologically nontrivial flat bands and tunable edge currents, driven by time-reversal symmetry breaking and ultrastrong light-matter interactions.
