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 a record-breaking laser fractional frequency instability of and a 12 mHz linewidth using a 68 cm room-temperature optical reference cavity, proving that state-of-the-art spectral purity is achievable without cryogenic cooling.
This paper calculates comprehensive multi-level and multi-term collisional depolarization, polarization-transfer, and population-transfer rates for solar helium I lines resulting from isotropic collisions with neutral hydrogen, providing essential data to improve the modeling of solar spectropolarimetry.
This paper demonstrates many cycles of syndrome extraction in a toric quantum error-correcting code using neutral atom arrays, achieving indefinite coherent operation through mid-circuit qubit measurement and reloading while showing that larger code distances yield lower logical error rates.
This paper reports the implementation of a room-temperature thorium-229 optical nuclear clock embedded in a calcium fluoride crystal that achieves high stability through rapid laser feedback, enabling competitive constraints on ultralight dark matter models by surpassing previous limits on strong force and quark couplings.
This paper presents a Hessian-based calibration method that leverages the low-rank structure of quantum-control landscapes to efficiently optimize high-dimensional waveforms for neutral atom gates, experimentally demonstrating rapid convergence and high fidelity (0.99902) for a robust controlled-Z gate on 171Yb qubits.
This paper theoretically demonstrates that a pair of strongly coupled qubits in a two-photon driven cavity exhibits hyperradiance as a signature of entanglement and can function as a quadrature-squeezed, two-photon source when an intracavity Kerr nonlinearity induces photon blockade.
This paper theoretically investigates ultra-cold dipolar atoms in radially coupled concentric annular traps, revealing how rotation and barrier strength induce particle imbalances, density modulations, and distinct vortex configurations—including unique Josephson vortices at ring junctions—that can be experimentally identified through characteristic interference patterns.
By rigorously solving the time-dependent Schrödinger equation for ionization driven by extreme ultraviolet pulses, this study reveals that photoelectron combs exhibit angle-dependent shifts and substructures due to full radiation pressure effects, while also demonstrating that rescattering causes a loss of coherence in these structures as the number of pulses increases.
This paper demonstrates that an interacting Rydberg vapour driven by a modulated laser field can effectively predict time series, with its learning capability significantly enhanced by emergent collective amplification near a non-equilibrium phase transition.
This paper theoretically demonstrates that tuning rotation frequency in Bose-Einstein condensates can induce a superfluid-to-supersolid transition and trigger re-entrant phases through a vortex-driven mechanism where quantized vorticity elevates the Goldstone mode to a finite-energy roton, thereby revealing a fundamental coupling between topological defects and crystalline order.
