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 rigorously establishes that dynamical quantum non-locality originates from the superposition principle by proving that the Wigner propagator reduces to its classical counterpart if and only if the Hamiltonian is at most quadratic, and introduces a measurable signed divergence that unifies the understanding of five distinct quantum phenomena ranging from non-local games to metrological gains.
This paper demonstrates that magnetic fields can tune the interactions between alkaline-earth Rydberg atoms to realize effective XXZ quantum spin models, revealing unique anisotropy behavior in Yb due to strong spin-orbit coupling and predicting the emergence of folded XXZ and supersolid phases in one- and two-dimensional systems.
This paper demonstrates that extending the Judd-Ofelt theory to account for 4f5d configuration effects significantly improves the description of Pr3+:YAG's luminescence properties, yielding more reliable spectroscopic data and confirming the feasibility of efficient laser operation at new wavelengths including 566 nm and 931 nm.
This paper proposes and demonstrates a hybrid visible-THz quantum interface where strong optical driving of polar emitters creates tunable Rabi-split states that couple to a THz channel, enabling the generation of high-fidelity steady-state entanglement between qubits through collective dissipative dynamics while allowing for complete optical control and readout.
The Rci-Q package extends the GRASP2018 suite by implementing an improved QED correction model that incorporates the Flambaum-Ginges radiative potential with new fitting prefactors, finite nucleus size corrections to self-energy, and the Wichmann-Kroll vacuum polarization potential.
This paper investigates how interaction asymmetry modifies the mean-field yrast spectrum of a two-component Bose gas in a ring, revealing that the emergence and stability of fractional-angular-momentum plane-wave states depend critically on whether intra-component interactions are weaker or stronger than inter-component interactions, leading to either continuous evolution or branch-crossing mechanisms.
This paper presents an analytical framework demonstrating that nonclassical radiation in strongly laser-driven quantum systems, such as high-order harmonic generation, emerges from the nonlinear dependence of the electronic dipole response on the quantized light-mode coordinate, enabling the engineering of squeezed states and Wigner-function negativity.
This paper presents a method for calculating electric-field-dependent -factors in symmetric top molecules and applies it to RaOCH to identify -doublet levels with small -factor differences, which is crucial for enhancing electron electric dipole moment (eEDM) experiments via laser cooling.
This paper introduces a new class of geometrically constructed, error-correcting control pulses that enable ultra-fast, robust state transitions for co-located spin ensembles without frequency selectivity, achieving milliradian precision and paving the way for 30-fold improvements in next-generation tests of the standard model and nuclear-spin quantum memories.
