This study demonstrates the observation of universal anyonic braiding phases in graphene interferometers at fractional quantum Hall states and by analyzing real-time three-state random telegraph noise, which reveals Aharonov-Bohm oscillations phase-shifted by corresponding to the fractional exchange statistics of anyons.
This paper demonstrates that Trotterized quantum circuits simulating near-thermal dynamics are significantly more robust to both gate and discretization errors than previously assumed, particularly on Quantinuum's trapped-ion hardware where error rates scale favorably with gate strength, a finding supported by analytical arguments, numerical simulations, and experiments utilizing a novel random product state ensemble.
This paper establishes a bulk-edge correspondence for continuous Hamiltonians modeling biased cold plasmas and photonics by identifying eight distinct phases, applying a bulk difference invariant to predict asymmetric edge modes at phase interfaces, and deriving tools to analyze the correspondence's limitations near singular phase transitions.
This paper proposes that Dzyaloshinskii-Moriya interactions induce and energetically pin Dirac nodes in the spinon spectrum of a Kagome spin liquid through a mechanism involving band inversion, Chern number changes, and the coupling to spinon orbital magnetization, offering an alternative to symmetry protection.
This paper introduces the semi-classical geometric tensor (SCGT) as a new geometrical framework that quantifies the intrinsic quantum obstruction between quantum and classical distinguishability by proving a matrix inequality that sharpens the standard bound between quantum and classical Fisher information matrices.
This study demonstrates that coating diamond surfaces with a thin titanium oxide (TiO) layer effectively eliminates background "dark" electron spins, thereby doubling the coherence time of near-surface nitrogen-vacancy centers and enabling more sensitive nanoscale quantum sensing.
The paper introduces SPARX, a deep learning framework that rapidly and accurately predicts broadband dark-field spectra of plasmonic nanostructures from limited RGB images by leveraging physical resonance relationships, thereby overcoming the speed and consistency limitations of conventional spectroscopic techniques.
This study reports the discovery of robust dissipationless transport and fractional conductance plateaus in hexagonal boron nitride/graphene/PbI2 heterostructures, attributing these phenomena to Chern junctions formed between moiré-modulated and conventional quantum Hall states driven by proximity-induced spin-orbit coupling.
This paper proposes a method for detecting and controlling nuclear spins by coupling them to megahertz mechanical resonators, demonstrating that measuring the resonator's frequency variance caused by fluctuating spin polarization enables single nuclear spin detection.
This paper classifies all quantum anomalous Hall phases in gated rhombohedral graphene with an arbitrary number of layers, demonstrating a bulk-edge correspondence and identifying topological phase transitions and quantized chiral edge charges as the displacement field varies relative to interlayer coupling.
