Runaway Gravitational Production of Dark Photons

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: We demonstrate that gravitational particle production (GPP) of a massive, Abelian, vector (Proca) field during inflation in the presence of nonminimal coupling to gravity may suffer from an instability which leads to runaway production of […]

Chemical Diversity on Small Scales — Abundance Analysis of the Tucana V Ultra-Faint Dwarf Galaxy

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Terese T. Hansen, Joshua D. Simon, Ting S. Li, Domani Sharkey, Alexander P. Ji | Summary: The growing number of Milky Way satellites detected in recent years has introduced a new focus for stellar abundance analysis. Abundances of stars in satellites have been used to probe […]

Impossible Symmetries and Conformal Gravity

Kavli Affiliate: Austin Joyce | First 5 Authors: Kurt Hinterbichler, Austin Joyce, GrĂ©goire Mathys, , | Summary: We explore the physics of relativistic gapless phases defined by a mixed anomaly between two generalized conserved currents. The gapless modes can be understood as Goldstone modes arising from the nonlinear realization of (generically higher-form) symmetries arising from […]

Quantum error thresholds for gauge-redundant digitizations of lattice field theories

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: In the quantum simulation of lattice gauge theories, gauge symmetry can be either fixed or encoded as a redundancy of the Hilbert space. While gauge-fixing reduces the number of qubits, keeping the gauge redundancy can provide code […]

COOL-LAMPS VI: Lens model and New Constraints on the Properties of COOL J1241+2219, a Bright z = 5 Lyman Break Galaxy and its z = 1 Cluster Lens

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Maxwell Klein, Keren Sharon, Kate Napier, Michael D. Gladders, Gourav Khullar | Summary: We present a strong lensing analysis of COOL J1241+2219, the brightest known gravitationally lensed galaxy at $z geq 5$, based on new multi-band Hubble Space Telescope (HST) imaging data. The lensed galaxy has […]
