  • Excitonic Instability Revealed by the Elastocaloric Effect in ${\mathrm{Ta}}_{2}{\mathrm{NiSe}}_{5}$

    Author(s): Elliott Rosenberg, Joss Ayres-Sims, Andrew Millis, David Cobden, and Jiun-Haw Chu Elastocaloric effect measurements on Ta2NiSe5 show that its phase transition at ~324 K is driven by a nonacoustic instability, rather than by an acoustic shear mode, strengthening the case that the transition is largely excitonic in nature.

  • Breaking the Intrinsic Absorption Limit for Arbitrarily Thin Conductive Films at Grazing Incidence

    Author(s): Yuxuan Liu, Ren-Hao Fan, Dong-Xiang Qi, Ruwen Peng, Yun Lai, Mu Wang, and Jie Luo Light grazing an ultrathin conductive film can be absorbed much more strongly than previously thought. [Phys. Rev. Lett. 136, 046902] Published Wed Jan 28, 2026

  • Provable and Verifiable Quantum Advantage in Sample Complexity

    Author(s): Marcello Benedetti, Harry Buhrman, and Jordi Weggemans In a sample-to-sample setting, quantum computation achieves the largest possible separation over classical computation. [Phys. Rev. Lett. 136, 040601] Published Tue Jan 27, 2026

  • Geomagnetic Constraints on Millicharged Dark Matter

    Author(s): Ariel Arza, Yuanlin Gong, Jing Shu, Lei Wu, Qiang Yuan, and Bin Zhu Dark matter having a small electric charge would presumably generate a magnetic-field variation on Earth’s surface, but observations find no such signal. [Phys. Rev. Lett. 136, 041001] Published Tue Jan 27, 2026

  • Thermopower Probe of Fractional Quantum Hall States in Monolayer Graphene

    Author(s): Nishat Sultana, Robert W. Rienstra, Kenji Watanabe, Takashi Taniguchi, Joseph A. Stroscio, D. E. Feldman, and Fereshte Ghahari Thermopower is more sensitive than resistivity in detecting certain fractional quantum Hall states in monolayer graphene. [Phys. Rev. Lett. 136, 046502] Published Tue Jan 27, 2026

  • Gravitational Wave Memory from Binary Neutron Star Mergers

    Author(s): Jamie Bamber, Antonios Tsokaros, Milton Ruiz, Stuart L. Shapiro, Marc Favata, Matthew Karlson, and Fabrizio Venturi Piñas The full displacement memory signal from binary neutron star mergers, including both the contribution from the gravitational waves themselves and from the electromagnetic, neutrino and baryonic ejecta is quantified using general relativistic magnetohydrodynamic simulations.

  • High-Power Picosecond Pulsed Kerr Soliton Microcombs

    Author(s): Liu Yang, Keisuke Ogawa, Ryomei Takabayashi, Yuta Mototani, Tatsuki Murakami, Hajime Kumazaki, Yongyong Zhuang, Xiaoyong Wei, and Shun Fujii Strong mode interactions in ultrahigh-Q crystalline microresonators produce a high-power, high-efficiency dissipative Kerr soliton regime revealing new nonlinear dynamics where localized mode crossings act as effective higher-order dispersion.
