Kavli Affiliate: Robert M. Wald | First 5 Authors: Kartik Prabhu, Gautam Satishchandran, Robert M. Wald, , | Summary: Infrared (IR) divergences arise in scattering theory with massless fields and are manifestations of the memory effect. There is nothing singular about states with memory, but they do not lie in the standard Fock space. IR […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Jose Maria Ezquiaga, Wayne Hu, Macarena Lagos, Meng-Xiang Lin, Fei Xu | Summary: Low-energy alternatives to General Relativity (GR) generically modify the phase of gravitational waves (GWs) during their propagation. As detector sensitivities increase, it becomes key to understand how these modifications affect the GW higher modes […]

Kavli Affiliate: Marcela Carena | First 5 Authors: Asher Berlin, Sergey Belomestnykh, Diego Blas, Daniil Frolov, Anthony J. Brady | Summary: This is a Snowmass white paper on the utility of existing and future superconducting cavities to probe fundamental physics. Superconducting radio frequency (SRF) cavity technology has seen tremendous progress in the past decades, as […]
Kavli Affiliate: Clarence Chang | First 5 Authors: Jonathan Asaadi, Dan Baxter, Karl K. Berggren, Davide Braga, Serge A. Charlebois | Summary: In the last decade, several photon counting technologies have been developed opening a new window for experiments in the low photon number regime. Several ongoing and future projects in HEP benefit from these […]

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Ezra Sukay, Gourav Khullar, Michael D. Gladders, Keren Sharon, Guillaume Mahler | Summary: We present COOL J1323+0343, an early-type galaxy at $z = 1.0153 pm 0.0006$, strongly lensed by a cluster of galaxies at z = $z = 0.353 pm 0.001$. This object was originally imaged […]
Kavli Affiliate: Brian D. Nord | First 5 Authors: Apriel K Hodari, Shayna B Krammes, Chanda Prescod-Weinstein, Brian D Nord, Jessica N Esquivel | Summary: The Community Engagement Frontier presents this set of three white papers, as part of Snowmass 2021. These papers address critical issues — Power Dynamics in Physics, Informal Socialization in Physics […]
Kavli Affiliate: Brian D. Nord | First 5 Authors: Apriel K Hodari, Shayna B Krammes, Chanda Prescod-Weinstein, Brian D Nord, Jessica N Esquivel | Summary: This paper addresses issues related to the process of informal socialization into physics, particularly for senior graduate students and postdoctoral scholars. Many physicists’ careers are built on the relationships they […]
