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 presents an efficient computational model that incorporates molecular structure effects to accurately determine low-energy muon transfer cross-sections from muonic hydrogen to molecular oxygen, thereby significantly improving agreement with theoretical calculations and aiding the analysis of the FAMU experiment.
Using a zero-range model for -wave interactions, this study demonstrates that the three-body recombination rate constant for identical fermions scales as rather than the conventional , while also deriving a perturbative correction term that significantly refines the temperature and interaction dependence near resonance.
This paper establishes sufficient conditions for finite-size quantum catalysis across various resource theories, revealing a phenomenon of "catalytic resonance" that allows for efficient transformations with minimal catalyst dimensions and connects these findings to multi-copy transformations.
This paper demonstrates a novel all-optical scheme using spatially engineered vector beams to generate synthetic gauge fields in ultracold atoms, enabling the creation of angular stripe phases with a significantly expanded parameter range and tunable topologically nontrivial giant skyrmions.
This paper evaluates and compares various calcium sources for laser ablation loading of ion traps, analyzing factors such as ease of use, plume characteristics, and spot lifetime to estimate the number of trappable atoms per pulse for quantum computing applications.
This paper theoretically proposes a driven-dissipative Dicke model with complex-valued couplings, realized via a driven atom tweezer array in an optical cavity, which exhibits a unique phase diagram for featuring or symmetry-breaking superradiant phases and a dynamically unstable normal phase separated by a first-order phase transition due to non-reciprocal forces.
This study demonstrates that ultracold fermions in a three-dimensional optical lattice exhibit a saturation of collisional resistivity at a value independent of interaction strength in the strongly interacting metallic regime, a phenomenon quantitatively explained by a renormalized two-body scattering matrix model.
This paper introduces radial gausslets, a generalized three-dimensional basis set for atomic systems that retains the computational advantage of diagonal electron-electron interaction terms while achieving high accuracy and compactness in Hartree-Fock and exact diagonalization calculations.
This study investigates interatomic Coulombic decay (ICD) in helium ion–argon dimer collisions using a coupled-channel two-center basis generator method, revealing that electron excitation to the state is the dominant ICD pathway and that lower-energy He projectiles significantly enhance this decay process.
This paper proposes a two-dimensional electron gas experiment to study electron scattering by a magnetic monopole, deriving a differential cross section via the eikonal approximation that matches the solenoid case while demonstrating that unpolarized electrons acquire spin polarization perpendicular to the current.
