Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper derives a general formula for the energy level contributions of nuclear tensor polarizability in two-body bound systems, demonstrating its role in mixing states of different orbital angular momenta, and specifically evaluates these effects on the hyperfine structure and S-D mixing in muonic deuterium.
This paper demonstrates that the interband Berry connection in an optical honeycomb lattice can be directly mapped by measuring the resonant excitation strength of ultracold fermionic atoms under periodic lattice modulation, revealing key geometric features such as transparency lines and irreducible Dirac strings between specific energy bands.
This paper experimentally demonstrates and theoretically validates magnetically induced transitions of the Cs 6SP line at 456 nm, which exhibit high intensity and large frequency shifts in magnetic fields, suggesting their potential for high-resolution optical frequency references and magnetometers in the blue spectrum.
This paper presents an improved analytical emission model based on a secondary-emission-surface approach that accurately predicts the angular intensity distribution and flux properties of primary effusive sources across the full range of molecular flow, from transparent to opaque regimes, to guide the design of efficient sources for atomic and molecular physics experiments.
Using high-precision x-ray spectroscopy of muonic chlorine atoms combined with advanced theoretical calculations, researchers determined the charge radii of stable Cl and Cl isotopes with an order-of-magnitude improvement in precision, resolving previous discrepancies in mirror nuclei trends and establishing new reference values for future studies.
This paper proposes a non-autoregressive learning framework that utilizes atomic trajectories as an auxiliary modality during training to enable fast, accurate, and dynamic ionic transport prediction from static structures without requiring sequential inference or trajectory data at inference time.
This paper investigates finite nuclear size corrections to magnetic-dipole hyperfine splitting in muonic hydrogenlike ions using a fully relativistic Dirac framework, presenting a systematic dataset of correction factors for various states and nuclear charge numbers while demonstrating the critical importance of realistic nuclear modeling for precision studies.
This paper calculates the ratio of low-mass -boson to Standard Model -boson contributions to parity nonconservation in hydrogen and deuterium, demonstrating that these light atoms offer a theoretically clean and highly sensitive environment for detecting hypothetical new vector bosons due to the rapid increase in the signal relative to the Standard Model background as nuclear charge decreases.
This paper theoretically investigates the transient dynamics in rubidium vapors triggered by the rapid turn-on of a strong resonant continuous-wave laser, demonstrating the formation of damped soliton or simulton trains before the system relaxes into a stationary state, while accounting for various broadening mechanisms and hyperfine structures.
This paper presents a technique combining electromagnetically induced transparency cooling with fluorescence imaging to successfully load, cool, and image Rb atom arrays in finite magnetic fields up to 10 G, achieving high readout fidelity and survival probability to enable future continuously-operated neutral atom quantum processors and sensors.
