This paper reports the synthesis and characterization of a phenalenyl dimer, demonstrating through inelastic electron tunneling spectroscopy and theoretical analysis that interphenalenyl exchange interactions and third-neighbor orbital hybridization govern its spin-1/2 singlet-triplet excitations, which are significantly renormalized by the underlying metal substrate.
By combining atomistic simulations and neutron spectroscopy, this study reveals that thermally induced Rayleigh surface phonons, which generate "thermal nanoquakes" with displacements vastly exceeding terrestrial earthquakes, are responsible for the linear scaling of low-energy vibrational density of states in diamond nanocrystals, thereby establishing a comprehensive framework for their vibrational dynamics.
This study demonstrates that inelastic excitations observed in the spin S = 1/2 phenalenyl radical on Au(111) via inelastic electron tunneling spectroscopy are of vibrational rather than magnetic origin, as confirmed by spatial intensity analysis and theoretical simulations.
This study demonstrates that depositing the spin-1/2 nanographene [2]triangulene on a ferromagnetic TbAu2 surface alloy induces a proximity-driven splitting of its Kondo resonance, revealing a spatially modulated magnetic interaction that establishes TbAu2 as a viable platform for probing and integrating open-shell nanographenes with magnetic substrates.
This study investigates the breakdown of the quantum anomalous Hall effect in V-doped (Bi,Sb)Te films under microwave irradiation, revealing that electron-hole puddle heating induces hopping transport that increases longitudinal resistance, thereby providing critical insights for GHz-range applications.
This study utilizes time-resolved measurements to demonstrate that current-induced magnetization reversal in quantum anomalous Hall systems is a thermally activated process driven by Joule heating within a disordered magnetic landscape, enabling the controlled manipulation of chiral edge states.
This study experimentally demonstrates the many-body ground state of a singlet diradicaloid on an ultrathin NaCl surface by combining tip-induced generation, atomic-scale scanning probe characterization, and multiconfigurational calculations to reveal strong electronic correlations in its geometric and electronic structures.
This paper investigates a triangular Aharonov-Bohm quantum network where tunable flat bands, controlled by magnetic flux, induce distinct signatures in the electronic specific heat, offering a novel thermal method for identifying momentum-independent energy levels in quantum systems.
This paper presents fully two-dimensional self-consistent screening calculations of a narrow GaAs/AlGaAs Hall bar with interior contacts, revealing how the interplay between compressible and incompressible electron regions under varying magnetic fields creates distinct galvanic, floating, and isolated regimes that dramatically alter current distribution and resistance.
This paper investigates how fine geometric features of the Fermi surface, such as local flattenings or nearly cylindrical strips, significantly influence the galvanomagnetic and high-frequency response of normal metals, with these effects being highly sensitive to the orientation of external magnetic fields and disturbance propagation directions.
