  • Strengthening Tungsten Diboride toward a Superhard Material by Ordered Vacancy Pairs

    Author(s): Chao Gu, Xiaojun Xiang, Xuefeng Zhou, Xiaohui Yu, Yusheng Zhao, and Shanmin Wang Planting vacancies into the atomic lattice of a brittle material increases its toughness and hardness. [Phys. Rev. Lett. 136, 106101] Published Thu Mar 12, 2026

  • Polar-Displacement Mechanism for Negative Poisson’s Ratio in Ferroelectric Perovskites

    Author(s): Xue Ma, Jinjing Zhang, Lianhua He, Shuai Yang, Fei Li, and Bin Xu The negative Poisson’s ratio in ferroelectric perovskites arises from bond-length preserving local polar displacements of atoms under strain. [Phys. Rev. Lett. 136, 106102] Published Thu Mar 12, 2026

  • Flow between Extremal One-Point Energy Correlators in QCD

    Author(s): Marc Riembau and Minho Son A calculation shows how the one-point energy correlator flows between its two extremal values corresponding to the quark and hadron degrees of freedom. [Phys. Rev. Lett. 136, 101901] Published Wed Mar 11, 2026

  • Multimode Single-Ring Photonic Molecule

    Author(s): Jinsheng Lu, Ileana-Cristina Benea-Chelmus, Vincent Ginis, Marcus Ossiander, Danilo Shchepanovich, and Federico Capasso A new ring-shaped resonator for light can do a job that normally requires at least two rings. [Phys. Rev. Lett. 136, 103803] Published Wed Mar 11, 2026

  • Beyond Poisson: First-Passage Asymptotics of Renewal Shot Noise

    Author(s): J. Brémont A framework for analyzing extreme events in non-Markovian systems with relaxation, from neuronal spiking to gene expression bursts, shows how burstiness universally modulates the baseline Arrhenius scaling, establishing a link between microscopic arrival statistics and macroscopic extreme-event kinetics. [Phys. Rev. Lett. 136, 107101] Published Wed Mar 11, 2026

  • Competing Magnetic Anisotropy and Domain-Wall Density for Optimizing Magnetization-Induced Water-Oxidation Enhancement

    Author(s): Anke Yu, Durgesh Kumar, Zizhao Gong, Leonhard Tannesia, Hasibur Rahaman, Pengfei Song, Tianze Wu, Ramu Maddu, Pinkesh Kumar Mishra, Xiao Renshaw Wang, S. N. Piramanayagam, and Zhichuan J. Xu Optimal spin-related enhancement of oxygen evolution reaction activity is shown to emerge from the balance between perpendicular magnetic anisotropy and the density of magnetic domain walls. [Phys. Rev. Lett. 136, 108001] Published Wed Mar 11...

  • Modeling the Cosmological Lyman-$α$ Forest at the Field Level

    Author(s): Roger de Belsunce, Mikhail M. Ivanov, James M. Sullivan, Kazuyuki Akitsu, and Shi-Fan Chen A new mathematical framework based on perturbation theory could yield new insights into cosmic structure and fundamental physics. [Phys. Rev. Lett. 136, 101001] Published Tue Mar 10, 2026
