This paper introduces AARDVARK, an unsupervised machine learning framework that combines UMAP dimensionality reduction with Gaussian process regression to enable efficient, real-time, and autonomous identification of electronic and chemical phases in spatially-resolved photoemission spectroscopy experiments.
This paper reports the discovery of twisted magnon frequency combs in ferromagnetic nanorings, demonstrating how their formation, mode density, and tunable spacing can be precisely controlled through geometric hole size and external magnetic fields via nonlinear coupling and angular momentum conservation.
This paper demonstrates that cubic Dresselhaus orbital coupling generates momentum-space hot spots and a significantly enhanced divergence coefficient, boosting the intrinsic orbital Hall conductivity by over an order of magnitude compared to linear Rashba-type coupling to enable giant orbital Hall responses.
This paper proposes and analyzes a novel platform for Majorana zero modes consisting of a quantum dot chain sandwiched between an s-wave superconductor and a spin-orbit semiconductor, demonstrating that the zero-energy retarded Green function effectively maps the system's topological phase diagram and spatial wave function characteristics in agreement with transfer matrix results.
This paper presents organic transistors embedded with sub-nanometer platinum nanoparticles at an ultrathin oxide interface that exhibit a large memory window, Coulomb blockade-like transport, and enhanced short-term plasticity, offering a promising platform for neuromorphic computing.
This paper demonstrates that AB-stacked MoTe/WSe heterobilayers at a specific hole doping can host topological Kondo semimetal and insulator ground states driven by chiral Kondo coupling between a Mott-localized MoTe layer and itinerant WSe electrons, with the latter state being stabilizable by random strain fields to achieve a quantized spin Hall effect.
This paper theoretically demonstrates that a classical bosonic mode, such as a magnon in an antiferromagnet or a phonon, can serve as a superior probe for resolving magnonic number states via effective dispersive couplings, outperforming traditional superconducting qubit sensors.
This paper presents a systematic framework for constructing all-bands-flat lattice Hamiltonians with broken time-reversal symmetry by threading magnetic flux through plaquettes and applying unitary transformations, resulting in compact localized states that host flux-dependent circulatory currents.
This paper presents a unified theoretical framework for surface polarization involving oblique dipole orientations in confined systems, demonstrating that near-field scattering techniques like s-SNOM offer superior sensitivity to these oblique dipoles compared to reflectance measurements, as validated by improved agreement with experimental data for monolayer WSe.
This paper investigates the critical behavior of Chern insulator transitions at a boundary, demonstrating that while chiral edge modes delocalize into the bulk, they retain a chiral structure and encode parity-odd anomaly coefficients in correlation functions, a framework applicable to general time-reversal breaking (2+1)d conformal field theories and higher-dimensional topological transitions.
