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 a method to resolve the ambiguity in vector magnetometry caused by anti-parallel magnetic fields by utilizing structured light and Fourier analysis of absorption profiles in optically polarized atomic vapor to achieve unambiguous, complete characterization of arbitrarily oriented magnetic fields.
This paper presents the first full-dimensional quantum scattering calculations for rovibrationally excited HD+HD collisions, identifying near-resonant transitions and low-energy resonances dominated by l=3 partial waves that agree with previous experimental cross sections and provide rate coefficients for temperatures ranging from 0.1 K to 200 K.
This paper presents computationally efficient higher-order mean-field and perturbative analytical methods to model photon statistics and radiation dynamics in chiral waveguide QED systems, successfully capturing complex many-body correlations and benchmarking against experimental results where exact treatments are infeasible.
This paper derives an analytic expression for the Doppler residual lineshape in thermal Rydberg ladder EIT, experimentally demonstrating a record-breaking two-photon energy resolution of 2.04 MHz (theoretically limited to 1.84 MHz) for Rubidium, which is approximately twice as narrow as previous estimates and measurements.
This paper presents exact analytical solutions for photon statistics in waveguide quantum electrodynamics within the thermodynamic limit, demonstrating that a second-order mean-field method captures exponentially enhanced superradiance followed by subradiance, while revealing that shot-to-shot fluctuations vanish and second-order coherence becomes trivial as the number of atoms approaches infinity.
This paper presents the design, implementation, and theoretical validation of a compact, modular, and cost-effective tabletop high-harmonics generation beamline utilizing a hollow capillary waveguide to produce intense, broadband extreme ultraviolet and soft X-ray pulses for ultrafast pump-probe spectroscopy of complex optoelectronic devices.
This paper presents an efficient, GPU-extendable finite-difference simulation framework that significantly outperforms conventional methods in modeling bubble-shaped Bose-Einstein condensates, enabling the identification of key parameters for their experimental realization in microgravity environments like the International Space Station.
This paper reports the first realization of a spin-resolved quantum-gas microscope for fermionic Sr, enabling site-resolved detection of all 10 spin states in SU(N) Fermi-Hubbard systems to probe exotic magnetism and magnetic correlations.
This paper identifies and characterizes two previously elusive families of core-bound excitations (varicose and fluting waves) on Gross-Pitaevskii vortices, detailing their dispersion relations across different wavelength limits and proposing a spectroscopic protocol for their experimental detection.
This paper demonstrates that combining the geometric Berry phase with non-Hermitian dissipation enables a fundamentally new amplification mechanism where slow parameter modulation converts a lossy oscillator system into one with gain, a phenomenon uniquely driven by the complex-valued Berry phase.
