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 a non-invasive, all-optical quantum-enhanced diagnostic technique using Rydberg electromagnetically induced transparency in trace rubidium vapor to achieve high-resolution 2D spatial mapping of electric fields within low-temperature plasma sheaths.
This review article consolidates over two decades of research on noise correlation spectroscopy, a technique that utilizes laser frequency noise to measure atomic coherence with high precision, covering its theoretical foundations, experimental implementations across various media, and future potential as a standard spectroscopic tool.
This paper investigates the breakdown of exact Floquet flat bands in a driven Rydberg chain beyond the PXP limit, identifying two distinct melting mechanisms—resonant pair production and virtual processes—and demonstrating how these effects lead to state-dependent dynamics, including exceptional stability for the vacuum, oscillatory behavior for the state, and the emergence of Floquet scars for the state.
This paper reports the theoretical calculations and experimental demonstration of two-photon Doppler-free spectroscopy for the Rydberg transition in ytterbium, highlighting its unique insensitivity to external perturbations and potential utility in quantum sensing applications such as clocks, electrometers, and thermometers.
This paper demonstrates that for shielded single-component ultracold dipolar molecular Fermi gases, the bottleneck of evaporative cooling is governed by universal threshold laws where the thermalization-to-loss ratio is more favorable in 2D than in 3D due to reduced Fermi suppression of rethermalization, suggesting 2D geometries are superior for achieving deep degeneracy.
This tutorial bridges the gap between theoretical quantum scattering concepts and practical numerical methods by deriving a coupled-channel framework using Dirac notation and Numerov's method to calculate cross sections for bimolecular collisions.
This paper projects that a single-domain Rb spinor Bose-Einstein condensate comagnetometer, utilizing its unique ability to suppress magnetic noise while enhancing sensitivity to exotic interactions, could achieve a sensitivity to proton monopole-dipole couplings more than five orders of magnitude beyond current laboratory limits, thereby probing light boson masses in the 0.09–70 meV/c range.
This study employs time-dependent density-functional theory to calculate Wigner time delays for iodoalkanes in the iodine giant-resonance region, revealing a robust, nearly isomer-independent behavior that starkly contrasts with the pronounced molecular variations reported in recent attosecond streaking experiments.
This paper reports the first successful transport of thousands of ions confined in a linear Paul trap over several kilometers, establishing a foundation for mobile trapped-ion quantum devices and the transfer of exotic ions between laboratories.
This paper investigates the crossover between bidirectional and unidirectional light-matter interaction models in optically dense emitter ensembles, demonstrating that spatial disorder induces a critical phase separation point independent of Doppler broadening, thereby validating the unidirectional waveguide approach for modeling systems with imperfect spatial ordering.
