Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper reports the successful development and demonstration of a compact, cost-effective cryogenic Penning trap utilizing a permanent magnet, which serves as both a functional testbed for the upcoming Shanghai Penning Trap and a versatile platform for ion trapping, cooling, and spectroscopic studies.
This article proposes and demonstrates a quantum sensing technique based on motional Raman transitions in a single trapped ion to achieve ultrasensitive, broadband detection of high-frequency electric fields with high precision in frequency, phase, and amplitude, surpassing previous methods by more than 800-fold in bandwidth while operating below the standard quantum limit.
This paper introduces a machine learning model, condensed into an analytical expression, that predicts the electric dipole moments of diatomic molecules using only atomic properties to screen the periodic table for molecules with the largest dipole moments and to reveal underlying chemical trends.
Motivated by applications in neutrino mass experiments and precision spectroscopy, this paper presents calculations of energy-dependent elastic scattering cross sections for hydrogen, deuterium, and tritium on helium isotopes, revealing that tritium scattering is significantly enhanced at low energies due to a near-threshold s-wave resonant bound state before converging to a geometric limit at higher energies.
This paper demonstrates the measurement of entanglement entropy and the observation of a disorder-induced transition from chaotic to localized dynamics in a programmable neutral-atom quantum simulator (QuEra's Aquila) by employing a novel randomised measurement protocol that bypasses the need for local gate control through the combination of local energy tuning and a global field.
This paper presents relativistic many-body calculations of the Landé -factor for lithium-like ions (), demonstrating that negative-energy states provide significant, state-dependent interelectronic-interaction corrections that reach up to 30% of the total contribution for the state at .
The authors present a simple, cost-effective method for generating tunable, phase-locked laser light with sub-Hz relative linewidth by using a laser diode to selectively amplify a single sideband of an electro-optically modulated seed laser.
This paper theoretically demonstrates that a continuous superradiant laser can be achieved by sequentially transporting two ensembles of atoms into a single cavity, showing that atomic synchronization ensures robust, narrow-linewidth emission suitable for metrological applications.
This work employs simulations of open quantum systems and the theory of quantum optimal control, specifically the Krotov method, to overcome noise-induced limitations in statically coupled exchange surface qubits, and demonstrates that high-precision operations are achievable through optimized experimental designs that surpass conventional Rabi driving.
This paper demonstrates that near-infrared field-induced dynamics within a molecular cation create an additional quantum pathway that significantly alters the sideband signals in attosecond interferometry, highlighting the need to account for such ionic coupling when interpreting molecular spectroscopy.
