SENSEI: First Direct-Detection Results on sub-GeV Dark Matter from SENSEI at SNOLAB

Kavli Affiliate: Michael Crisler | First 5 Authors: SENSEI Collaboration, Prakruth Adari, Itay M. Bloch, Ana M. Botti, Mariano Cababie | Summary: We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. With an exposure of 534.9 gram-days from well-performing sensors, we select events containing […]

Flux coupled tunable superconducting resonator

Kavli Affiliate: Clarence Chang | First 5 Authors: Juliang Li, Pete Barry, Tom Cecil, Marharyta Lisovenko, Volodymyr Yefremenko | Summary: We present a design and implementation of frequency-tunable superconducting resonator. The resonance frequency tunability is achieved by flux-coupling a superconducting LC-loop to a current-biased feedline; the resulting screening current leads to a change of the […]

A New Probe of Gravitational Parity Violation Through (Non-)Observation of the Stochastic Gravitational-Wave Background

Kavli Affiliate: Daniel Holz | First 5 Authors: Thomas Callister, Leah Jenks, Daniel Holz, Nicolás Yunes, | Summary: Parity violation in the gravitational sector is a prediction of many theories beyond general relativity. In the propagation of gravitational waves, parity violation manifests by inducing amplitude and/or velocity birefringence between right- and left-circularly polarized modes. We […]
