Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper presents new level-resolved ionization cross-section calculations for Te I–III using the Flexible Atomic Code to address the lack of non-thermal electron interaction data, demonstrating that configuration average approximations yield accurate results that significantly improve ionization balance models for kilonova ejecta.
This paper proposes a robust, scalable scheme for deterministically loading single microwave-shielded molecules into optical tweezer arrays with high fidelity and low entropy by utilizing interaction blockade to prevent multiparticle occupancy, thereby enabling large-scale polar molecule arrays for quantum technologies.
The authors report a breakthrough in compact vapor-cell clock technology by developing a 25-liter molecular iodine optical clock that achieves a record-breaking fractional frequency instability of , surpassing previous vapor-cell limits by nearly an order of magnitude through a novel monolithic, temperature-controlled design.
Motivated by the ATOMKI anomalies, this study employs the Gaussian Expansion Method to predict X17-induced Lamb shifts and hyperfine splittings in muonic atoms up to Z=15, identifying specific isotopes like muonic deuterium, helium ions, and silicon-29 as promising probes to distinguish between vector and pseudoscalar fifth-force mediators.
This paper demonstrates a sustainable neutral-atom quantum computing framework that maintains high-fidelity two-qubit gates (~99.8%) across deep, repetitive circuits by integrating mid-circuit operations, including non-destructive erasure detection and in-situ cooling, to actively manage motional heating and atom loss for continuous error correction.
This study revisits Cherepkov's theory of spin-resolved photoionization in chiral molecules to demonstrate that the ten independent parameters governing spin- and enantio-sensitive observables can be reduced to moments of three fundamental geometric pseudovectors arising solely from electric dipole interactions.
This study integrates Rydberg-atom-based broadband sensing with a 1D ResNet deep learning model to construct spectral fingerprints of partial discharge signals, achieving robust recognition and early warning capabilities for electrical insulation diagnostics without manual feature engineering.
This paper resolves conflicting interpretations of double ionization of helium by demonstrating that the original Kheifets et al. calculations remain valid and can be reproduced either by incorporating the second Born approximation or by using a corrected ground state similar to that proposed by Jones and Madison.
This paper outlines a nonperturbative formalism based on coupled Lippmann-Schwinger integral equations to calculate total and differential cross-sections for multiphoton ionization of one- and two-electron atoms in strong laser fields, demonstrating its application through models of a square well potential and the hydrogen atom.
The paper demonstrates that employing the Kramers-Henneberger Hamiltonian for time-independent multi-photon ionization calculations offers a significant computational advantage over length and velocity gauges by utilizing finite, well-defined dipole matrix elements for free-free transitions, thereby enabling accurate results for both one- and two-electron atomic systems.
