  • Acoustic Analogy of Quantum Baldin Sum Rule for Optimal Causal Scattering

    Author(s): Sichao Qu, Zixiong Yu, Erqian Dong, Min Yang, and Nicholas X. Fang Sound wave scattering can be increased in one frequency range only by reducing scattering in another range, according to experiments—a discovery relevant for acoustic engineering. [Phys. Rev. Lett. 136, 226902] Published Fri Jun 05, 2026

  • Crossed Surface Flat Bands in Three-Dimensional Superconducting Altermagnets

    Author(s): Yuri Fukaya, Bo Lu, Keiji Yada, Yukio Tanaka, and Jorge Cayao Higher dimensional topological phases in three-dimensional superconducting altermagnets characterized by zero-energy surface crossed flat bands indicate the interplay between altermagnetic and superconducting symmetries. [Phys. Rev. Lett. 136, 226001] Published Thu Jun 04, 2026

  • Observation of Acoustic Magnetochiral Anisotropy in $α$ Quartz

    Author(s): Munkhtuguldur Altangerel, S. Badoux, C. Proust, D. Vignolles, and G. L. J. A. Rikken Acoustic magnetochiral anisotropy is observed in a diamagnetic crystal of α quartz. [Phys. Rev. Lett. 136, 226303] Published Thu Jun 04, 2026

  • Acoustic Bound Pair States in the Continuum Induced by Off-Site Two-Body Interactions

    Author(s): Zhenhang Pu, Chunbo Hua, Hailong He, Liping Ye, Jiuyang Lu, Weiyin Deng, Manzhu Ke, and Zhengyou Liu A novel many-body bound state in the continuum induced entirely by uniform off-site 2-body interactions is observed by mapping a quantum 1D Bose-Hubbard model onto a 2D macroscopic phononic crystal. [Phys. Rev. Lett. 136, 226501] Published Thu Jun 04, 2026

  • Observable Gravitational Wave Strain at Second Order

    Author(s): Guillem Domènech, Shi Pi (皮石), and Ao Wang (王奥) The ambiguity in associating gravitational waves with transverse-traceless components of the metric at second order in perturbation theory is resolved by computing the detector response to second order for the first time. [Phys. Rev. Lett. 136, 221402] Published Wed Jun 03, 2026

  • Electron Recoil via Sample Momentum Transfer in Optical-Mode Excitation

    Author(s): Akira Yasuhara, Yamato Kirii, and Takumi Sannomiya Momentum-resolved EELS provides the first direct evidence that electrons impart measurable momentum to planar samples during mode excitation. [Phys. Rev. Lett. 136, 226901] Published Wed Jun 03, 2026
