  • Clock Precision beyond the Standard Quantum Limit at ${10}^{−18}$ Level

    Author(s): Y. A. Yang, Maya Miklos, Yee Ming Tso, Stella Kraus, Joonseok Hur, and Jun Ye An entanglement-enhanced optical clock achieves unprecedented precision of 10−18 with 2dB quantum noise squeezing. [Phys. Rev. Lett. 135, 193202] Published Fri Nov 07, 2025

  • Breaking a Superfluid Harmonic Dam: Observation and Theory of Riemann Invariants and Accelerating Sonic Horizons

    Author(s): Shashwat Sharan, Judith Gonzalez Sorribes, Patrick Sprenger, Mark A. Hoefer, P. Engels, Boaz Ilan, and M. E. Mossman An experimental and theoretical study of sonic horizons emerging from the dam-break problem in a Bose-Einstein condensate confined in an anisotropic harmonic trap is presented. Measurements, analysis, and numerics reveal the formation of a sonic horizon that undergoes acceleration due to harmonic co… [Phys. Rev. Lett...

  • Spin Polarization in Strong-Field Ionization as Sensor of Trapped Electron Orbits

    Author(s): Linxuan Zhang, Stefanos Carlström, Olga Smirnova, Misha Ivanov, and Difa Ye We show how spin polarization of photoelectrons produced in strong-field ionization of noble-gas atoms can be used to detect highly unexpected electron orbits created in strong, circularly polarized near-infrared fields. In such fields, ionization is expected to generate photoelectrons rapidly movin… [Phys. Rev. Lett. 135, 193201] Published Thu Nov 06, 2025

  • Mass-Gap Description of Heavy Impurities in Fermi Gases

    Author(s): Xin Chen, Eugen Dizer, Emilio Ramos Rodríguez, and Richard Schmidt We present a unified theory that connects the quasiparticle picture of Fermi polarons for mobile impurities to the Anderson orthogonality catastrophe for static impurities. By operator reordering of the underlying many-body Hamiltonian, we obtain a modified fermionic dispersion relation that feature… [Phys. Rev. Lett. 135, 193401] Published Thu Nov 06, 2025

  • Phase-Space Nonseparability, Partial Coherence, and Optical Beam Shifts

    Author(s): Yahong Chen and Sergey A. Ponomarenko As a paraxial wave packet is reflected or refracted from a planar interface separating two material media, it experiences spatial and angular shifts of its center position with respect to predictions of the geometrical ray picture. These in-plane and out-of-plane beam shifts are known as Goos-Hänche… [Phys. Rev. Lett. 135, 193801] Published Wed Nov 05, 2025

  • Measurement of the $g$ Factor of Ground-State $^{87}\mathrm{Sr}$ at the Parts-per-Million Level Using Co-Trapped Ultracold Atoms

    Author(s): Premjith Thekkeppatt, Digvijay, Alexander Urech, Florian Schreck, and Klaasjan van Druten We demonstrate nuclear magnetic resonance of optically trapped ground-state ultracold $^{87}\mathrm{Sr}$ atoms. Using a scheme in which a cloud of ultracold $^{87}\mathrm{Rb}$ is co-trapped nearby, we improve the determination of the nuclear $g$ factor, ${g}_{I}$, of atomic $^{87}\mathrm{Sr}$ by mor… [Phys.

  • Atomic Real-Space Imaging of Molecular Statics and Dynamics at Confined States

    Author(s): Yusheng Liu (刘雨生), Liang Xu (许亮), Xiao Chen (陈晓), Ning Huang (黄宁), Mengmeng Ma (马蒙蒙), Huiqiu Wang (王挥遒), Bin Song (宋斌), Tao Cheng (程涛), Fei Wei (魏飞), and Boyuan Shen (申博渊) Atomic imaging of molecules and intermolecular interactions is important for obtaining a deeper understanding of the related physics and chemistry. At a confined state in reticular matrix, molecular architecture can be stabilized for studying its static and dynamic...
