Author(s): Di Liu, Han Liu, and Zheng Xi Optical spin textures with nontrivial topology hold promise for structured light and photonic information processing, yet their generation typically relies heavily on externally structured light with care. This raises questions about their universal existence and true robustness. Here, we uncover an… [Phys. Rev. Lett. 136, 073801] Published Fri Feb 20, 2026

Author(s): Yankun Dou, Peizeng Li, Xiaoxiao Long, Peipei Ge, Yongkai Deng, Chengyin Wu, Qihuang Gong, and Yunquan Liu We present a joint experimental and theoretical investigation of nondipole effects in strong-field double ionization of xenon atoms driven by circularly polarized 800 nm laser fields. We observe that the ${\mathrm{Xe}}^{2+}$ ion momentum distribution in the laser polarization plane is Gaussian. The … [Phys. Rev. Lett. 136, 073201...

Author(s): Zixuan Zeng, Shoukang Yang, Shuhua Deng, and Bo Yan We report the realization of a blue-detuned magneto-optical trap (BDM) of BaF molecules. The ($1+1$) type BDM and ($1+2$) type conveyor-belt MOT (CB-MOT) are explored. While the ($1+1$) BDM provides only a weak trapping force, the CB-MOT significantly compresses the molecular cloud, achieving a Gaus… [Phys. Rev. Lett. 136, 073402] Published Thu Feb 19, 2026

Author(s): Weijie Liang, Weiping Zhang, and Keye Zhang Moiré physics has transcended spatial dimensions, extending into synthetic domains and enabling novel quantum phenomena. We propose a theoretical model for a two-dimensional (2D) moiré time crystal formed by ultracold atoms, induced by periodic perturbations applied to a nonlattice trap. Our analysi… [Phys. Rev.

Author(s): Ying Liang, Bao-Yun Dong, Zijian Xiong, and Xue-Feng Zhang Rydberg atom triangular arrays in an optical cavity serve as an ideal platform for understanding the interplay between geometric frustration and quantized photons. Using a large-scale quantum Monte Carlo method, we obtain a rich ground state phase diagram. Around half-filling, the infinite long-rang… [Phys. Rev. Lett. 136, 073602] Published Wed Feb 18, 2026

Author(s): Xin-Rui Mao, Bang Wu, Wei-Jie Ji, Shao-Lei Wang, Wang-Zhe Li, Han-Qing Liu, Haiqiao Ni, Zhichuan Niu, and Zhiliang Yuan A novel single-photon source made of a quantum dot embedded in a Dirac cavity provides outstanding performance metrics.

Author(s): Vanessa Wachter, Silvia Viola Kusminskiy, Gabriel Hétet, and Benjamin A. Stickler Recent experiments demonstrate all-electric spinning of levitated nanodiamonds with embedded nitrogen-vacancy spins. Here, we argue that such gyroscopically stabilized spin rotors offer a promising platform for probing and exploiting quantum spin-rotation coupling of particles hosting a single spin … [Phys. Rev.
