  • Apparent Parity Violation in the Observed Galaxy Trispectrum

    Author(s): Pritha Paul, Chris Clarkson, and Roy Maartens A fully relativistic treatment of the statistics of galaxy distributions may explain the parity violation recently seen in the galaxy trispectrum. [Phys. Rev. Lett. 133, 121001] Published Tue Sep 17, 2024

  • Two-Gap Superconductivity and the Decisive Role of Rare-Earth $d$ Electrons in Infinite-Layer Nickelates

    Author(s): Zhenglu Li and Steven G. Louie Superconducting gaps on the Fermi surface of infinite-layer nickelates show a phonon-mediated pairing mechanism, suggesting that these superconductors are not conventional after all. [Phys. Rev. Lett. 133, 126401] Published Tue Sep 17, 2024

  • Spin-Dependent Localization of Helical Edge States in a Non-Hermitian Phononic Crystal

    Author(s): Junpeng Wu, Riyi Zheng, Jialuo Liang, Manzhu Ke, Jiuyang Lu, Weiyin Deng, Xueqin Huang, and Zhengyou Liu The spin-dependent hybrid skin-topological effect is experimentally realized on a non-Hermitian phononic crystal, which might lead to new methods for non-Hermitian wave manipulations. [Phys. Rev. Lett. 133, 126601] Published Tue Sep 17, 2024

  • Legacy of Boson Clouds on Black Hole Binaries

    Author(s): Giovanni Maria Tomaselli, Thomas F. M. Spieksma, and Gianfranco Bertone Gravitational-wave signals from black hole mergers could reveal the presence of “gravitational atoms”—black holes surrounded by clouds of axions or other light bosons. [Phys. Rev. Lett. 133, 121402] Published Mon Sep 16, 2024

  • Giant Photocaloric Effects across a Vast Temperature Range in Ferroelectric Perovskites

    Author(s): Riccardo Rurali, Carlos Escorihuela-Sayalero, Josep Lluís Tamarit, Jorge Íñiguez-González, and Claudio Cazorla Ultraviolet photons induce potassium niobate to behave like a potent solid-state refrigerant, according to new calculations. [Phys. Rev. Lett. 133, 116401] Published Tue Sep 10, 2024

  • Cluster State as a Noninvertible Symmetry-Protected Topological Phase

    Author(s): Sahand Seifnashri and Shu-Heng Shao A qubit chain described by the cluster Hamiltonian can host a nondegenerate gapped topological phase protected by a noninvertible symmetry. [Phys. Rev. Lett. 133, 116601] Published Tue Sep 10, 2024

  • Spin Dynamics across Metallic Layers on the Few-Femtosecond Timescale

    Author(s): Romain Géneaux, Hung-Tzu Chang, Alexander Guggenmos, Renaud Delaunay, François Légaré, Katherine Légaré, Jan Lüning, Tymur Parpiiev, Ilana J. P. Molesky, Bethany R. de Roulet, Michael W. Zuerch, Sangeeta Sharma, Martin Schultze, and Stephen R. Leone Researchers use ultrashort laser pulses to trigger a spin-aligned electron flow on the few-femtosecond timescale—opening up a possible path toward faster spintronic devices. [Phys. Rev...
