A 107, 010001 (2023) – Published 4 January 2023   Editors' Suggestion Search for entanglement in the decay dynamics and anisotropic emission of a pair of H(2p) atoms produced by XUV photodissociation of H2 A. Dochain, B. Fabre, C. Lauzin, and X. Urbain Phys. Rev. A 107, 013109 (2023) – Published 19 January 2023 In this article, the authors experimentally investigate the possibility to produce a pair of entangled photons from the photodissociation of H2. They study the dynamics of the two-photon emission and introduce a simple model, assuming a transition from Hund's case (a) to Hund's case (c), to reproduce the measured angular distributions satisfactorily.     Featured in Physics Editors' Suggestion Intense continuous cold-atom source William Huntington, Jeremy Glick, Michael Borysow, and Daniel J. Heinzen Phys. Rev. A 107, 013302 (2023) – Published 6 January 2023 Synopsis:Cold-Atom Beams without Laser Cooling The authors demonstrate an intense, continuous cold atomic beam generated via postnozzle seeding of a supersonic 4He jet with 7Li atoms, which is comparable to the highest flux sources based on laser cooling. The technique could potentially be widely applicable to any paramagnetic atom or molecule.     Editors' Suggestion Unified lattice sums accommodating multiple sublattices for solutions of the Helmholtz equation in two and three dimensions Dominik Beutel, Ivan Fernandez-Corbaton, and Carsten Rockstuhl Phys. Rev. A 107, 013508 (2023) – Published 12 January 2023 The authors derive expressions for lattice sums of solutions of the Helmholtz equation in two and three dimensions that can be efficiently evaluated in numerical implementations. The results are applicable to complex materials involving multiple sublattices, describing systems including metasurfaces and moire superlattices.     Editors' Suggestion Exact solutions for the electromagnetic fields of a flying focus D. Ramsey, A. Di Piazza, M. Formanek, P. Franke, D. H. Froula, B. Malaca, W. B. Mori, J. R. Pierce, T. T. Simpson, J. Vieira, M. Vranic, K. Weichman, and J. P. Palastro Phys. Rev. A 107, 013513 (2023) – Published 19 January 2023 A laser beam's peak intensity may be programmed to move at an arbitrary velocity by adjusting the focal time and location of its frequencies, temporal slices, or annuli. Such "flying focus" beams show promise in enabling new laser-matter applications. To assess these possibilities, the authors analytically describe the electromagnetic fields of flying-focus pulses with arbitrary polarization and orbital angular momentum.       American Physical Society: 1 Physics Ellipse, College Park, MD 20740 ©2023 American Physical Society | All rights reserved   You are receiving this email because you are subscribed to Table of Content alerts.
