Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
Using state-of-the-art tensor network methods, this study demonstrates that long-range interacting quantum spin chains exhibit robust, long-lived Kardar-Parisi-Zhang (KPZ) superdiffusive spin transport despite lacking integrability, a phenomenon attributed to their proximity to the integrable Inozemtsev family and observable in various experimental platforms like Rydberg atom arrays.
This paper establishes a comprehensive framework for quantifying quantum advantage in latency-constrained distributed decision-making by incorporating realistic hardware constraints like finite operation times and entanglement rates, and proposes a time-multiplexed trapped-atom network architecture capable of meeting these stringent operational criteria for applications such as financial markets and power grids.
This paper presents an experimental scheme for a programmable, dynamic two-dimensional quasiperiodic optical lattice with ultracold atoms that achieves significant phase noise suppression and high modulation bandwidth, enabling full translational and phasonic control to explore complex quantum dynamics in quasicrystals.
This paper theoretically investigates the coherent propagation of resonant Bessel beams through Th-doped CaF crystals, demonstrating that their unique orbital angular momentum and non-uniform profiles can enhance excitation control and reveal the spatial distribution of nuclear quantization axes via nuclear forward scattering.
This paper presents a novel, scalable Fresnel zone plate design that combines the high resolution of static plates with the dynamic reconfigurability of spatial light modulators to generate versatile atomic waveguides ideal for ultracold atom Sagnac interferometry.
This paper presents a complete theoretical calculation of the muonic hydrogen (H) ground-state hyperfine splitting, incorporating direct quantum electrodynamic and recoil corrections alongside proton structure effects derived from hydrogen data, to yield a prediction of eV with precision exceeding 1 ppm.
This paper reports a 4-K cryogenic platform that utilizes high numerical aperture optics and dual-wavelength trapping to achieve 5000-second lifetimes and prepare defect-free arrays of up to 1024 atoms, significantly advancing prospects for large-scale quantum computing.
This paper introduces a symmetrization scheme that preserves the Mermin-Wagner theorem to resolve pseudo phase transitions in the 2D Hubbard model, applying it within a GW-covariance framework to accurately calculate Green's and spin-spin correlation functions that align with DQMC benchmarks while satisfying fundamental many-body relations.
This paper presents a high-resolution magnetic imaging system utilizing a free-induction-decay optically pumped magnetometer with a double-pass optical configuration and scanning micromirror to achieve sub-millimeter spatial resolution and sub-picotesla sensitivity, successfully enabling noninvasive diagnostics of integrated circuits and batteries.
This paper presents an all-optical method using double dressing to create spherical shell-shaped traps for ultracold atoms in microgravity, demonstrating a realistic configuration for rubidium ensembles that achieves strong transverse confinement with minimal heating.
