This study demonstrates that identifying single-photon emitters in hexagonal boron nitride using atomic-resolution ADF-STEM is fundamentally limited by sample thickness (beyond ~17 layers) and susceptible to misidentification due to residual threefold astigmatism, rendering the technique unreliable for the thicker flakes typically used in photonic research.
This paper proposes a non-abelian geometric quantum energy pump that utilizes transitionless driving and a counterdiabatic term to coherently transport states within a degenerate subspace, where the net energy transfer is determined by the non-abelian Berry-curvature tensor and the Euler class, offering potential applications as a quantum transducer, charger, or metrological tool across various physical platforms.
This paper demonstrates a tunable double-junction transmon qubit featuring a Josephson potential with magnetic-flux-controlled harmonics, where spectroscopy reveals a second harmonic amplitude up to ~10% and identifies a flux sweet spot that eliminates dispersive shifts by balancing couplings to internal and qubit modes.
This paper introduces a new generation of quantum-enabled spintronic antennas that overcome the efficiency limitations of traditional miniaturized devices, enabling embedded applications, single-element beam steering, and stealth capabilities for secure communication.
This paper demonstrates that nonlinear magnon interactions, specifically pump-induced nondegenerate three-magnon splitting, dynamically generate double anticrossings by creating two distinct magnon populations that independently couple to the Kittel mode.
This paper presents a self-consistent multiscale ensemble Monte Carlo framework for monolayer MoS that integrates first-principles-validated scattering mechanisms with a channel model to accurately predict intrinsic transport properties, field-effect transistor characteristics, and gas sensing responses to various adsorbates.
This paper establishes that a $PT$-symmetric heterostructure of a topological insulator and a -wave altermagnet can generate a pure bulk spin photovoltaic effect—producing dc spin currents without charge currents—when the Néel vector lies in the $xy$-plane, a phenomenon controlled by light polarization and the system's topological phase.
This paper demonstrates that dual-gated electrostatic control in InAs/GaInSb/InAs trilayer quantum wells effectively suppresses parasitic bulk and edge conduction, thereby enabling robust and quantized helical edge channel transport across a wide electric-field range in III-V quantum spin Hall insulators.
Using Johnson-noise thermometry in a bilayer graphene-hexagonal boron nitride moiré superlattice, researchers demonstrate that the thermal conductance of various topological states is universally quantized in units determined solely by their Chern number, establishing thermal transport as a robust probe for moiré topological matter.
This paper establishes the complete group-theoretical classification of odd-parity spin splitting in collinear magnets, revealing previously unexplored high-order -, -, and -wave classes, and demonstrates their realization in specific materials alongside their distinct impacts on anomalous transport phenomena.
