The subatomic world is a realm where matter behaves in ways that defy our everyday intuition, and this category explores the fundamental building blocks of our universe. From the intricate dance of quarks inside a proton to the strange properties of electrons, these studies reveal the deep rules that govern everything from the smallest particles to the largest stars.

Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper proposes integrated optical configurations utilizing standing-wave nodes to suppress spontaneous photon scattering and eliminate unwanted coherent couplings, thereby enabling high-fidelity, parallel trapped-ion entangling gates with approximately an order-of-magnitude reduction in required laser power compared to conventional running-wave approaches.
This paper presents a systematic study of interchannel quantum interference in below-threshold nonsequential double ionization by deriving analytical phase conditions, introducing Earth Mover's Distance-based statistical metrics to quantify channel contributions, and identifying key factors that govern the hierarchy of interference mechanisms in the recollision-excitation with subsequent ionization pathway.
This paper presents a computationally efficient (1+1)-dimensional quantum model, extending the Eckhardt-Sacha approach to diatomic systems, which successfully describes nonsequential double ionization in homonuclear diatomic molecules and reproduces key experimental features like the knee structure.
This paper presents a fully relativistic derivation of the thermal one-loop self-energy correction for hydrogen-like systems, which accurately accounts for various quantum-mechanical effects like Stark and Zeeman shifts and provides essential data for reducing uncertainty in high-precision atomic experiments.
This paper presents a comprehensive comparative analysis of partial-wave expansion convergence for bound-electron self-energy calculations in Feynman and Coulomb gauges to address accuracy limitations in Lamb shift predictions for highly charged ions, while also discussing methods to improve convergence.
This paper investigates a previously unreported lineshape-asymmetry-caused shift (LACS) in atomic interferometers arising from frequency-chirped laser fields during Ramsey pulses, demonstrating that this shift scales as and thus becomes a significant metrological error source for compact devices with short free-evolution times.
This paper proposes that a long-range parity-violating interaction mediated by the exchange of two neutrinos effectively acts as a contact term in atomic systems, producing a correction that resolves the existing discrepancy between the Standard Model prediction and experimental measurements of cesium parity violation while yielding weak mixing angle and weak charge values consistent with the Standard Model.
This paper utilizes a newly developed Light-Matter DMRG algorithm to investigate a generalized Dicke-Ising model in high-Q cavities, revealing how cavity-induced multimode structures can optimize spin entanglement, drive transitions to superradiant phases, and stabilize quantum spin nematic states for potential quantum state engineering.
This paper presents a breakthrough in Rydberg-atom electric field sensing by overcoming conventional low-frequency limitations through auxiliary modulation and a paraffin-coated vapor cell, enabling electrode-free detection across a wideband range from 0.5 Hz to 10 kHz with state-of-the-art sensitivities.
This paper presents the first dual-channel closed-loop atomic beam interferometer that overcomes the intrinsic half-fringe dynamic-range limit by independently tracking and compensating for rotation and acceleration phases, thereby enabling unambiguous inertial measurements nearly two orders of magnitude beyond conventional limits while achieving high long-term stability.
