This paper theoretically demonstrates that analyzing photon statistics under resonant excitation allows for the discrimination between continuous and discrete spectral diffusion models in solid-state emitters, offering deeper insights into emission stability and clarifying the mechanisms behind recent experimental observations of B centers in hexagonal boron nitride.
This paper introduces the Atomic Single Electron Transistor, a novel scanning probe based on a single atomic defect in a van der Waals material, which achieves unprecedented spatial resolution and sensitivity to directly image the electrostatic potential landscape of graphene-hexagonal boron nitride moiré lattices, revealing a C6 symmetric potential with a magnitude that significantly exceeds current theoretical predictions.
This study demonstrates that valley splitting variations in an Intel-manufactured SiGe/Si/SiGe quantum dot array exhibit spatial correlations across both sub-100nm and micrometer scales, confirming that microscopic alloy disorder is the dominant factor and providing essential insights for designing scalable silicon-based quantum computers.
This paper establishes a theoretical and numerical framework demonstrating that long-range magnetostatic dipolar interactions break the energy degeneracy of bulk chiral skyrmions, specifically stabilizing Heusler antiskyrmions into square-lattice crystals while leaving Bloch skyrmions unaffected and slightly shrinking Néel skyrmions.
This paper demonstrates that dissipation in a periodically driven Rashba nanowire coupled to an s-wave superconductor induces both topological and trivial edge-localized Majorana 0- and -modes, significantly modifying the system's topological phase diagram and enabling the creation of topological phases in non-topological setups.
This study demonstrates that graphene/thin hBN/-RuCl heterostructures exhibit robust, non-volatile ferroelectric-like switching driven by electrically controllable interfacial charge transfer, a mechanism confirmed to be electrostatic and independent of magnetic fields or structural symmetry breaking.
This paper proposes a mechanism using lattice sum rules in non-Hermitian topological square-root insulators to enforce exceptional deficiency, where the entire energy spectrum consists of exceptional points, leading to unique dynamical signatures like static broadband and non-Abelian adiabatic state amplification.
This paper reports the observation of correlated interlayer quantum Hall states in large-angle alternating twisted trilayer graphene, characterized by spin-resolved helical edge modes at charge neutrality and an interlayer excitonic quantum Hall state at a specific filling factor.
This paper employs a systematic Schrieffer-Wolff transformation to derive an effective Hamiltonian for Josephson junctions that recovers the conventional cosine potential while simultaneously revealing how Bogoliubov quasiparticles induce correlated dynamics and how higher-order terms naturally generate Josephson harmonics linked to microscopic junction properties.
This paper presents an exact quantization framework for superconducting circuits that derives dressed mode frequencies and constructs a convergent Hamiltonian by synthesizing the Josephson junction's driving-point admittance into a canonical Cauer ladder network, enabling systematic diagonalization across all coupling regimes without requiring artificial ultraviolet cutoffs.
