- Competition between Geometrical Frustration and the Kondo Effect in CePdAl Revealed by High-Resolution Magnetization 04/09/2026Author(s): Yusei Shimizu, Shota Nakamura, Yoichi Ikeda, Yohei Kono, Shunichiro Kittaka, Toshiro Sakakibara, and Yosikazu IsikawaCePdAl is a heavy-fermion compound with a quasi-kagome structure, where geometrical frustration competes with the Kondo effect. Using a high-sensitivity magnetometer, we observe clear first-order metamagnetic transitions without magnetization plateaus in CePdAl at 80 mK, indicating a lifting of frus…[Phys. Rev.

- Nucleation, Creep, and Dynamic Tensile Fracture Are Described by Extended LEFM 04/09/2026Author(s): Yuval Paz, Meng Wang, Mokhtar Adda-Bedia, and Jay FinebergWe experimentally validate a new description of brittle tensile fracture that extends linear elastic fracture mechanics (LEFM) to account for the 2D geometry of propagating cracks in plates of finite thickness, $W$. We show that cracks nucleate below the Griffith length at a critical stress threshol…[Phys. […]Yuval Paz, Meng Wang, Mokhtar Adda-Bedia, and Jay Fineberg

- Resonant Excitation of Surface Plasmon for Wakefield Acceleration by Beating GW Lasers on Smooth Cylindrical Surface 04/09/2026Author(s): Bifeng Lei, Hao Zhang, Alexandre Bonatto, Bin Liu, Javier Resta-López, Matt Zepf, Guoxing Xia, and Carsten WelschWe present a theoretical and numerical study of resonant surface-plasmon (SP) excitation driven by the beating of two copropagating laser pulses on a smooth cylindrical plasma-vacuum interface. Analytical formulas for the SP dispersion relation, field amplitude, geometric coupling […]Bifeng Lei, Hao Zhang, Alexandre Bonatto, Bin Liu, Javier Resta-López, Matt Zepf, Guoxing Xia, and Carsten Welsch
