This paper demonstrates that rhombohedral 3-, 4-, and 5-layer graphene spontaneously hosts a doubly degenerate, interaction-driven non-Abelian Chern band with at filling , characterized by an emergent gauge structure driven by Fock exchange interactions.
This study employs a combined first-principles and Wannier-based model to reveal that the direct-to-indirect bandgap transition in layered MoS is driven not only by interlayer - coupling but also critically by previously overlooked - and - orbital interactions between neighboring sulfur atoms.
This paper presents an improved analytical model for metallic tunnel junctions that offers greater accuracy than the traditional Simmons model by deriving new formulas for tunneling current and conductance at finite voltage and temperature, which align more closely with the Wentzel-Kramers-Brillouin approximation and demonstrate significant practical differences when fitted to experimental data.
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 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 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.
This paper presents a deep learning-based pipeline using a U-Net CNN to automatically tune 300 mm FDSOI quantum dots by segmenting charge stability diagrams, achieving an 80% success rate in locating the single-charge regime and offering a scalable path toward high-throughput qubit automation.
