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.

Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper reports the first demonstration of a cesium-based laser-atomic oscillator (Cs-LAO) that functions as a self-oscillating atomic clock and earth-field magnetometer with short-term frequency instability around and magnetic sensitivity near 100 fT/, paving the way for truly chip-scale atomic devices.
This paper demonstrates the deterministic preparation of arbitrary two-component product states of fermionic Li atoms in an 88 optical tweezer array with over 98.5% motional ground-state fidelity, establishing a fast, scalable, and programmable architecture for low-entropy fermionic quantum simulation.
This paper reviews recent experimental and theoretical advances in understanding dineutron clusters within neutron-rich nuclei, highlighting evidence from halo nuclei and unbound systems, the role of few-body theories in interpreting decay processes, and the potential connection to four-neutron clusters and universal few-body physics.
This paper introduces STEMGym, a benchmark demonstrating that in autonomous scanning transmission electron microscopy, optimizing the perception pipeline yields significantly greater dose efficiency than employing advanced adaptive navigation strategies, thereby reframing where machine learning efforts should be prioritized.
This paper demonstrates that dissipative quantum systems can achieve rapid state manipulation by employing a cooperative "bang-drift-bang" strategy where coherent pulses strategically reorient the system onto fast relaxation channels, allowing the environment to drive the majority of the transfer and resulting in significant geometric amplification and speedup over passive relaxation timescales.
This paper demonstrates all-optical control of birefringence in a cold ytterbium atomic ensemble by using an off-resonant dressing beam to induce tunable, polarization-dependent light shifts that manipulate the probe light's polarization state without any external magnetic field.
This study uses real-time time-dependent density functional theory coupled with Ehrenfest molecular dynamics to demonstrate that while the net ionization of water clusters (n=1–4) remains relatively constant with size, increasing cluster size significantly enhances proton-mediated dynamics, leading to a sharp rise in H-ejection, stable H-transfer, and dissociation propensity driven by topology-level nuclear changes rather than ionization magnitude alone.
This paper proposes a fault-tolerant hybrid quantum architecture that combines cavity QED-based atom-photon entangling gates with measurement-based quantum computing to achieve scalable, high-connectivity quantum processing with a demonstrated photon-loss threshold of approximately 2.6% per gate.
This paper reformulates trapped-atom light-matter interaction using classical modulation theory by separating mean and fluctuation operators to derive an accurate, analytically tractable Bessel-function approximation for transition couplings that bridges classical and quantum descriptions.
This study achieves the first direct imaging of ultrafast enantioselective orientation dynamics in isolated chiral molecules by using unidirectional coherent rotation induced by femtosecond laser pulses to reveal mirror-image out-of-plane orientations for 2-methyloxirane enantiomers via time-resolved Coulomb explosion imaging.
