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.

At Gist.Science, we track every new preprint in this field as it appears on arXiv, ensuring you stay ahead of the curve. For each discovery, we provide both a clear, plain-language explanation of the core ideas and a detailed technical summary for those who want to dive deeper into the mathematics and methodology.

Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.

Symmetry and Quantum Interference in the Attosecond Domain

This review examines the interplay of symmetry and quantum interference in the attosecond domain by analyzing photoelectron momentum distributions to demonstrate how tailored laser fields, quantum-orbit methods, and target properties enable control over ultrafast electron dynamics, with a focus on photoelectron holography and nonsequential double ionization, while also exploring the potential of non-classical light states for further manipulation.

Parallel Omnidirectional Atom Rearrangement with Dynamic Holograms

This paper demonstrates a method for rapid, parallel, and three-dimensional atom rearrangement in optical tweezer arrays using dynamic holograms from a single kilohertz-rate spatial light modulator and a warm-start weighted Gerchberg-Saxton algorithm, successfully assembling a 2078-site ytterbium kagome lattice with 99.0% mean filling.

Fate of Discrete Time Crystals in Finite-Size Cavity QED Systems

This paper demonstrates that finite-size non-mean-field fluctuations in the open Dicke model induce non-monotonic decay of transient Discrete Time Crystals, a phenomenon accurately captured by the stochastic Truncated Wigner Approximation but missed by second-order cumulant expansions, revealing three distinct dynamical regimes with significant implications for experiments on finite atomic ensembles.

Zemach radii and nuclear structure effects in hyperfine splitting of lithium isotopes

This paper resolves the long-standing discrepancy between effective and elastic Zemach radii in lithium isotopes by demonstrating that nuclear polarizability effects, which are negligible in 7^7Li but dominant in 6^6Li, constitute the primary source of isotope-dependent nuclear corrections to hyperfine splitting in light atoms.

Quantum simulation of the Dicke model in a two-dimensional ion crystal

This paper demonstrates that a two-dimensional crystal of approximately 100 trapped ions can realize the Dicke model to experimentally observe non-equilibrium phenomena such as dynamical phase transitions, chaotic dynamics, and two-mode squeezing, thereby establishing large ion crystals as a scalable platform for investigating quantum light-matter interactions and generating resources for quantum-enhanced sensing.

Hidden Perturbative Structure in Attosecond Streaking

This paper reveals a hidden perturbative structure in inherently multiphoton attosecond streaking by filtering inversion-odd responses to isolate a characteristic angular-momentum propensity that survives electron correlation, thereby establishing a general spectroscopic framework for analyzing atomic, molecular, and solid-state systems.
