Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper addresses the theoretical blind spot of predicting where quantum detection events occur by comparing quantitative predictions from various proposed solutions to the screen problem, demonstrating that these models yield distinguishable results even in simple, far-field experiments achievable with current technology.
This paper presents state-of-the-art theoretical predictions for rotational levels in muonic, kaonic, and antiprotonic atoms using a unified nonrelativistic QED framework, demonstrating that improved accuracy could enable high-precision determinations of nuclear properties and tests of hypothetical long-range hadronic interactions.
This paper presents computer simulation results demonstrating that different numerical approaches yield identical Stark profiles for the krypton He-beta line and its satellites under inertial confinement fusion conditions, while also analyzing the impact of various physical effects on these line shapes.
Using data from the Global Network of Optical Magnetometers for Exotic physics searches (GNOME), researchers conducted a comprehensive search for a gravitationally bound solar axion halo, finding no significant signals but establishing stringent new upper limits on axion-proton couplings that surpass existing astrophysical bounds by over two orders of magnitude for quadratic coupling scenarios.
This paper presents new, improved calculations of Stark-broadened profiles for the ionized helium He II 4686 line by extending a computer simulation framework to incorporate hyperbolic trajectories for perturbing particles, thereby providing more accurate data for analyzing helium-atmosphere DO white dwarfs.
This paper reports a room-temperature laser system stabilized to an ultrastable cavity with crystalline AlGaAs coatings that achieves a record-low fractional frequency instability of , surpassing the Brownian noise limit of dielectric coatings while identifying coating birefringence fluctuations as a key noise source and demonstrating a feed-forward method to significantly reduce acceleration-induced frequency noise.
This review presents a bottom-up theoretical framework for electric dipole moments (EDMs) that traces the connection from fundamental CP-violating interactions at the quark-gluon level to observable EDMs in nucleons, nuclei, atoms, and molecules, emphasizing the role of chiral perturbation theory and the complementarity of various systems in identifying the sources of CP violation beyond the Standard Model.
This review article explores how cavity quantum electrodynamics (QED) enables quantum-enhanced metrology by utilizing time-reversal and interaction-based readout protocols to decode entangled many-body states, thereby transforming inaccessible quantum information into experimentally measurable signals.
This paper demonstrates that microwave shielding on the rotational transition effectively prevents destructive collisions in ultracold polar molecules while avoiding the formation of two-molecule bound states that cause 3-body recombination, thereby eliminating the need for complex double-field shielding schemes.
This paper investigates how repulsive interactions between condensed and thermal atoms in Bose-Einstein condensates distort time-of-flight expansion profiles, demonstrating that neglecting these interactions leads to significant errors in parameter estimation and proposing a simulation-based fitting approach that yields more accurate condensed fraction results than traditional Bose-enhanced models.
