  • Laser Excitation of the $^{229}\mathrm{Th}$ Nuclear Isomeric Transition in a Solid-State Host

    Author(s): R. Elwell, Christian Schneider, Justin Jeet, J. E. S. Terhune, H. W. T. Morgan, A. N. Alexandrova, H. B. Tran Tan, Andrei Derevianko, and Eric R. Hudson Researchers have made the most precise measurement to date of the excited nuclear state of thorium-229, a candidate isotope for an ultraprecise nuclear clock. [Phys. Rev. Lett. 133, 013201] Published Tue Jul 02, 2024

  • Noise Level of a Ring Laser Gyroscope in the Femto-Rad/s Range

    Author(s): Angela D. V. Di Virgilio, Francesco Bajardi, Andrea Basti, Nicolò Beverini, Giorgio Carelli, Donatella Ciampini, Giuseppe Di Somma, Francesco Fuso, Enrico Maccioni, Paolo Marsili, Antonello Ortolan, Alberto Porzio, and David Vitali Absolute angular rotation rate measurements with sensitivity better than prad/s would be beneficial for fundamental science investigations. In this regard, large frame Earth based ring laser gyroscopes are...

  • High-Fidelity Detection of Large-Scale Atom Arrays in an Optical Lattice

    Author(s): Renhao Tao, Maximilian Ammenwerth, Flavien Gyger, Immanuel Bloch, and Johannes Zeiher Recent advances in quantum simulation based on neutral atoms have largely benefited from high-resolution, single-atom sensitive imaging techniques. A variety of approaches have been developed to achieve such local detection of atoms in optical lattices or optical tweezers. For alkaline-earth and alk… [Phys. Rev.

  • Hyperbolic Shear Metasurfaces

    Author(s): Enrico M. Renzi, Emanuele Galiffi, Xiang Ni, and Andrea Alù The introduction of hyperbolic shear metasurfaces that support ultraconfined hyperbolic surface modes with symmetry-tailored axial dispersion and loss redistribution makes possible the generalization of the features of shear polaritons to metasurfaces.

  • Non-Hermitian Delocalization in a Two-Dimensional Photonic Quasicrystal

    Author(s): Zhaoyang Zhang, Shun Liang, Ismaël Septembre, Jiawei Yu, Yongping Huang, Maochang Liu, Yanpeng Zhang, Min Xiao, Guillaume Malpuech, and Dmitry Solnyshkov Theoretical and experimental studies suggest that both Hermitian and non-Hermitian quasicrystals show localization due to the fractal spectrum and to the transition to diffusive bands via exceptional points, respectively. Here, we present an experimental study of a dodecagonal photonic...

  • Time Refraction and Time Reflection above Critical Angle for Total Internal Reflection

    Author(s): Lior Bar-Hillel, Alex Dikopoltsev, Amit Kam, Yonatan Sharabi, Ohad Segal, Eran Lustig, and Mordechai Segev We study the time reflection and time refraction of waves caused by a spatial interface with a medium undergoing a sudden temporal change in permittivity. We show that monochromatic waves are transformed into a pulse by the permittivity change, and that time reflection is enhanced at the vicinity of… [Phys. Rev. Lett. 132, 263802...

  • Realizing Altermagnetism in Fermi-Hubbard Models with Ultracold Atoms

    Author(s): Purnendu Das, Valentin Leeb, Johannes Knolle, and Michael Knap Altermagnetism represents a type of collinear magnetism, that is in some aspects distinct from ferromagnetism and from conventional antiferromagnetism. In contrast to the latter, sublattices of opposite spin are related by spatial rotations and not only by translations and inversions. As a result, a… [Phys. Rev.
