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.
At Gist.Science, we track every new preprint in this field as it appears on arXiv, ensuring you stay ahead of the curve. For each discovery, we provide both a clear, plain-language explanation of the core ideas and a detailed technical summary for those who want to dive deeper into the mathematics and methodology.
Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper demonstrates that within a fixed hyperangular channel of a harmonically trapped gas, the breathing mode retains exact radial gaps with no forbidden spectral weight due to a novel first-order cancellation of perturbations, while also deriving a scaling for sum-rule estimates and noting the need for separate derivations regarding three-dimensional contact corrections.
This paper demonstrates a power modulation feedback protocol that suppresses the AC Stark shift in a two-photon rubidium optical frequency reference by a factor of 1000, enabling simultaneous short-term and long-term stability improvements while characterizing the resulting frequency noise limitations.
This paper demonstrates rapid, repeatable Rydberg-state hopping between 65S1/2 and 63D5/2 states in a cavity-free rubidium system using a wavemeter-locked digital feedback loop, achieving sub-MHz stability and enabling reemergent dissipative time-crystal oscillations for adaptive, multi-band field sensing.
This paper proposes a universally optimal protocol for fully charging a two-level quantum battery using a bipartite quantum charger, demonstrating how quantum coherence can be harnessed to charge multiple batteries and how the underlying dynamics can be adapted for active state resetting in quantum computing.
This paper investigates dissipative phase transitions in a parametrically amplified quantum Rabi model with two-photon decay, revealing a unique "inverted" superradiant regime characterized by a tricritical point and identifying the universality classes and scaling exponents that govern the system's critical behavior.
This paper investigates electron emission from hydrogen atoms induced by antiproton impact at intermediate energies using the one-centre Basis Generator Method, demonstrating that the resulting energy-differential cross sections agree well with other pseudostate-based approaches.
This paper proposes using quantum mirrors as network nodes where propagating coherent states mediate interactions between control qubits to achieve high-fidelity quantum teleportation, state transfer, and entanglement swapping that are robust against optical errors and scale exponentially with photon number.
This paper theoretically demonstrates that spatially inhomogeneous effective masses of dark-state polaritons, engineered via control fields in a two-dimensional electromagnetically induced transparency system, can create trapping potentials to tailor their motion and enable potential Bose-Einstein condensation.
This paper presents the first experimental measurement of the Lévy parameter from time-resolved backward fluorescence in hot rubidium vapor, demonstrating that while the extracted aligns with forward transmission and steady-state fluorescence results, backward photons exhibit a significant contribution from single scattering events even at high densities, unlike their forward counterparts.
This paper demonstrates that polar molecules trapped in rearrangeable optical tweezer arrays serve as a versatile quantum simulator for realizing and microscopically probing coherent many-body dynamics in XXZ and XYZ spin models, including phenomena such as quantum walks, magnon bound states, and pair creation.
