  • Dynamical Mean-Field Theory of Complex Systems on Sparse Directed Networks

    Author(s): Fernando L. Metz A generalized dynamical mean-field theory allows computation of the phase diagram of sparse and heterogeneous networks. [Phys. Rev. Lett. 134, 037401] Published Fri Jan 24, 2025

  • Enhanced Strange Metallicity due to Hubbard-$U$ Coulomb Repulsion

    Author(s): Andrew Hardy, Olivier Parcollet, Antoine Georges, and Aavishkar A. Patel A model of electrons that has a particular Coulomb repulsion and is coupled to a 2D bosonic bath shows a quantum critical point where traditional Fermi-liquid physics breaks down, resulting in a so-called strange metal. [Phys. Rev. Lett. 134, 036502] Published Thu Jan 23, 2025

  • Glass Transition in Monolayers of Rough Colloidal Ellipsoids

    Author(s): Jian Liang, Xuan Feng, Ning Zheng, Huaguang Wang, Ran Ni, and Zexin Zhang Roughing up the surfaces of particles in a colloidal system can smooth its transition into a glassy state. [Phys. Rev. Lett. 134, 038202] Published Thu Jan 23, 2025

  • Biased Ensembles of Pulsating Active Matter

    Author(s): William D. Piñeros and Étienne Fodor Ensembles of particles that actively pulsate in size which are also biased to select certain rare configurations can exhibit complex emergent behaviors that depend on system geometry. [Phys. Rev. Lett. 134, 038301] Published Thu Jan 23, 2025

  • Optimal Reconstruction of the Hellings and Downs Correlation

    Author(s): Bruce Allen and Joseph D. Romano A theoretical analysis places limits on the precision for inter-pulsar correlations contained in the Hellings and Downs curve. [Phys. Rev. Lett. 134, 031401] Published Wed Jan 22, 2025

  • Energy Relaxation and Dynamics in the Correlated Metal ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$ via Terahertz Two-Dimensional Coherent Spectroscopy

Armitage Energy relaxation rates in Sr2RuO4 probed with THz 2D coherent spectroscopy are strongly subdominant compared to the previously measured momentum relaxation rates. [Phys. Rev. Lett. 134, 036501] Published Wed Jan 22, 2025

  • Single-Electron Quantization of Dark Current in Quanta Image Sensors

    Author(s): Joanna Krynski, Daniel McGrath, Alexandre Le Roch, Sarah Holloway, Lucrezia Migliorin, Cédric Virmontois, and Vincent Goiffon A CMOS-based image sensor with very low noise levels allows observation of the quantization of dark current generation rate of stray electron/hole pairs in unilluminated photodetectors.
