This paper demonstrates that exciting nitrogen-vacancy (NV) ensembles at the NV0 zero-phonon line (575 nm) induces spin-selective electron tunneling that converts NV- to NV0 while preserving spin polarization, thereby enabling the previously discarded NV0 fluorescence to contribute to the measurable spin contrast and improve sensing sensitivity.
This study employs a comprehensive Molecular Dynamics framework to demonstrate that magnesium ion doping at surface sites significantly enhances the chemical stability of hydroxyapatite, offering optimized guidelines for developing advanced dental materials to combat tooth decay.
Using heat kernel methods, this paper demonstrates that the Atiyah–Singer index theorem extends to non-Hermitian Dirac operators, proving that their index remains topologically protected provided the operators are diagonalizable and satisfy specific ellipticity conditions.
This paper presents a physics-based model incorporating both intrinsic and extrinsic loss mechanisms to explain the temperature-dependent quality factor limits of epitaxial AlN acoustic resonators, validated through experimental measurements from 6.5 K to 300 K and benchmarked against high-frequency HBAR data to guide the design of cryogenic microwave components for quantum hardware.
Using time-resolved photoluminescence spectroscopy on MoSe/graphene heterostructures, this study demonstrates that sub-nanometer-range exciton transfer is governed by charge tunneling rather than dipolar interactions, as evidenced by a consistent ps transfer time that vanishes when a 1 nm hexagonal boron nitride spacer is introduced.
This paper predicts the emergence of nontrivial topological magnon states in skyrmionium lattices with zero topological charge by introducing the concept of weighted magnetic flux and mapping the system to the Haldane model, thereby challenging conventional wisdom and proposing experimental methods to validate these findings through magnon thermal Hall conductivity.
This paper demonstrates that pillar-based phononic crystals on suspended silicon nitride membranes can coherently control thermal transport at sub-Kelvin temperatures, achieving up to an order-of-magnitude reduction in thermal conductance, although the coherent theory fails to predict results for larger lattice constants due to diffusive scattering caused by surface roughness.
This paper demonstrates that periodically modulated defects in one-dimensional metallic networks can induce emergent symmetry-protected topological phases, such as a Su-Schrieffer-Heeger network and a robust Thouless charge pump, offering a defect-engineering approach to realizing tunable topological matter distinct from traditional atomic Hamiltonian engineering.
This paper provides a comprehensive overview of spin qubit platforms, detailing their physical implementations, theoretical foundations, and various proposed mechanisms for achieving long-range coupling to enable scalable quantum information processing.
This paper presents a surrogate-accelerated hierarchical Bayesian calibration framework that successfully derives data-informed dissipative particle dynamics models for commercial ultrasound contrast agents by inferring their mechanical parameters from force spectroscopy data across multiple bubble diameters.
