  • X-Ray-Induced Quenching of the $^{229}\mathrm{Th}$ Clock Isomer in ${\mathrm{CaF}}_{2}$

    Author(s): Ming Guan et al. Recent studies have shown that the lifetime of the isomeric $^{229}\mathrm{Th}$ doped in crystals can be shortened by x-ray or laser irradiation, a phenomenon referred to as isomer quenching. We investigate the temperature dependence of x-ray-induced quenching in $^{229}\mathrm{Th}:{\text{CaF}}_{2}$… [Phys. Rev. Lett. 136, 013203] Published Thu Jan 08, 2026

  • Time-Dependent Hole States in Multiconfigurational Time-Dependent Hartree-Fock Approaches: A Time-Domain Generalization of Extended Koopmans’ Theorem

    Author(s): Zhao-Han Zhang, Yang Li, Himadri Pathak, Takeshi Sato, Kenichi L. Ishikawa, and Feng He We introduce a framework for resolving electron-hole dynamics within wave-function-based multiconfigurational time-dependent Hartree-Fock (MCTDHF) theory. Central to this framework is a time-domain generalization of the extended Koopmans’ theorem, which rigorously defines time-dependent hole states … [Phys. Rev. Lett. 136, 013204] Published Thu...

  • Temperature Dependence of $p$-Wave Contacts in a Harmonically Trapped Fermi Gas

    Author(s): Kenta Nagase, Hikaru Takahashi, Soki Oshima, and Takashi Mukaiyama The temperature dependence of so-called p-wave interactions in an ultracold atomic gas has been measured for the first time. [Phys. Rev. Lett. 136, 013402] Published Thu Jan 08, 2026

  • Low-Energy Free-Electron Nonclassical Lasing

    Author(s): Mai Zhang, Yu Wang, Chang-Ling Zou, Lei Ying, Qiongyi He, Guang-Can Guo, and Chun-Hua Dong Harnessing a beam of slow free electrons in artificial photonic structures offers a tunable platform for studying quantum optics without the need for heavy physical equipment. Here, we present a theory of nonclassical lasing, demonstrating how incoherent electrons in photonic crystal cavities can co… [Phys. Rev. Lett. 136, 013603] Published...

  • Extensive Manipulation of Transition Rates and Substantial Population Inversion of Rotating Atoms Inside a Cavity

    Author(s): Yan Peng, Yuebing Zhou, Jiawei Hu, and Hongwei Yu We investigate the transition rates of a centripetally accelerated atom inside a high-quality cavity and show that they can be extensively tuned by adjusting the cavity resonance and the rotation frequency. Crucially, while inertial atoms cannot be excited in vacuum, rotation induces spontaneous exc… [Phys. Rev. Lett. 136, 013202] Published Tue Jan 06, 2026

  • Optical Excitation and Stabilization of Ultracold Field-Linked Tetratomic Molecules

    Author(s): Bijit Mukherjee and Michał Tomza We propose a coherent optical population transfer of weakly bound field-linked (FL) tetratomic molecules (tetramers) to deeper FL bound states using stimulated Raman adiabatic passage. We consider static-electric-field shielded polar alkali-metal diatomic molecules and corresponding FL tetramers in … [Phys. Rev. Lett. 136, 013401] Published Tue Jan 06, 2026

  • Matrix Phase-Space Representations for Gaussian Boson Sampling

    Author(s): Peter D. Drummond, Alexander S. Dellios, and Margaret D. Reid We introduce coherent matrix phase-space distributions. These use conservation laws and symmetries to improve the accuracy and speed of quantum phase-space representations. As an example, this is applied to the validation of low-loss Gaussian boson sampling (GBS) quantum computational advantage expe… [Phys. Rev. Lett. 136, 013601] Published Tue Jan 06, 2026
