  • Photoinduced Metal-to-Insulator Transitions in 2D Moiré Devices

    Author(s): Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo, Birui Yang, Dihao Sun, Luke Holtzman, Juseung Oh, Katayun Barmak, Cory R. Dean, James C. Hone, Nathaniel Gabor, Eric A. Arsenault, and Xiaoyang Zhu A laser-based approach rapidly injects charge into moiré materials and drives metal-to-insulator transitions. [Phys. Rev. Lett. 136, 206502] Published Tue May 19, 2026

  • Raman Optical Activity Induced by Ferroaxial Order in ${\mathrm{NiTiO}}_{3}$

    Author(s): Gakuto Kusuno, Takeshi Hayashida, Takayuki Nagai, Hikaru Watanabe, Rikuto Oiwa, Tsuyoshi Kimura, and Takuya Satoh Raman optical activity, a phenomenon usually observed in systems where inversion or time-reversal symmetry is broken, arises in a centrosymmetric, nonmagnetic crystal due to ferroaxial order. [Phys. Rev. Lett. 136, 206902] Published Tue May 19, 2026

  • Directionality-Induced Jamming in Multiplex Networks

    Author(s): Mateo Bouchet, Alejandro Tejedor, Xiangrong Wang, and Yamir Moreno In multiplex networks, directed links between layers hinder diffusion and break the system up, preventing it from converging to a steady state. [Phys. Rev. Lett. 136, 207401] Published Tue May 19, 2026

  • Correlation-Driven Ultrafast Exciton Diffusion in Hubbard-Regime Moiré Superlattices

    Author(s): Huan Liu, Haowen Xu, Shihong Chen, Rui Han, Zejun Sun, Mingxin Xu, Shuchun Huang, Xiushuo Zhang, Li Huang, Jianbin Luo, and Dameng Liu Ultrafast microscopy reveals that exciton flow in moiré superlattices can be switched on or off by competing Hubbard interactions and correlated electron phases, enabling quantum control of energy transport. [Phys. Rev. Lett. 136, 206302] Published Mon May 18, 2026

  • Dissipation-Shaped Quantum Geometry in Nonlinear Transport

    Author(s): Zhichao Guo, Xing-Yuan Liu, Hua Wang, Li-kun Shi, and Kai Chang Nonlinear transport as a probe of quantum geometry is not universal and is contingent on the specific dissipation mechanism, not just its strength. [Phys. Rev. Lett. 136, 206303] Published Mon May 18, 2026

  • Finite-Frequency Fluctuation-Response Inequality

    Author(s): Andreas Dechant Researchers derive a universal limit linking noise and response to perturbations in systems far from equilibrium. [Phys. Rev. Lett. 136, 207101] Published Mon May 18, 2026

  • Spinless and Spinful Charge Excitations in Moiré Fractional Chern Insulators

    Author(s): Miguel Gonçalves, Juan Felipe Mendez-Valderrama, Jonah Herzog-Arbeitman, Jiabin Yu, Xiaodong Xu, Di Xiao, B. Andrei Bernevig, and Nicolas Regnault Large-scale exact diagonalization yields the first direct microscopic computation of spinless and spinful quasiparticle charge gaps in a fractional Chern insulator. [Phys. Rev. Lett. 136, 196503] Published Thu May 14, 2026
