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 demonstrates the first real-time application of a GNSS-based correction method to synchronize free-running Rubidium and Caesium atomic clocks with UTC, achieving a residual time difference within ±15 ns and eliminating apparent drift.
This paper demonstrates that utilizing passively phase-stable standing waves within an integrated optical control system enables rapid, multi-mode laser cooling of trapped calcium ions to the quantum ground state, significantly outperforming conventional running-wave schemes in cooling speed, bandwidth, and final phonon occupancy.
This paper demonstrates a scalable, polarization-selective quantum light modulator by engineering dual-species atom arrays to break in-plane symmetry and achieve complete reflection of specific polarization components through cooperative subradiant modes.
This paper presents comprehensive Large-scale Multiconfiguration Dirac-Hartree-Fock (MCDHF) and Relativistic Configuration Interaction (RCI) calculations for 99 low-lying energy levels of beryllium, demonstrating excellent agreement with experimental data and providing reliable predictions for excitation energies, radiative transition rates, lifetimes, and other atomic parameters essential for astrophysical plasma diagnostics.
This paper proposes a minimal model of frustrated hardcore bosons on a -flux ladder that generates exact quantum many-body scars, offering a cross-platform experimental realization in cold atom and Rydberg atom systems to benchmark coherence and explore nonergodic dynamics.
This paper introduces deterministic unitary protocols that approximate imaginary-time evolution for ground-state preparation using multi-copy registers and controlled-SWAP operations, analyzing trade-offs between circuit depth and width in tree versus "hedge" architectures while demonstrating the potential of mid-circuit post-selection and platform-specific implementations.
This paper presents a piezoelectrically tunable Fabry-Perot cavity that achieves exceptional thermal stability and frequency precision at approximately 5°C, thereby eliminating the need for external active feedback systems in atomic physics experiments such as ultra-stable superradiant lasers.
This paper employs valence perturbation theory to efficiently calculate high partial wave contributions and estimate truncation corrections, thereby improving the reliability of theoretical error assessments in high-accuracy calculations of polyvalent atoms.
This paper provides the first concise analytical derivation of the Ericson transition in stochastic quantum scattering using the Heidelberg approach, proving the emergence of a universal Gaussian distribution for scattering matrix elements and validating these results through comparison with microwave experiments and numerical simulations.
This paper demonstrates that a radio-frequency-driven dissipative Rydberg gas of cesium atoms exhibits a tunable time-crystalline phase that, under heterodyne conditions, displays synchronization phenomena and generates a frequency comb, a behavior successfully modeled by both a four-level mean-field theory and a classical Van der Pol oscillator.
