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 degenerate trion liquid in atomic double layers

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Raghav Chaturvedi, Liguo Ma, Patrick Knuppel, Kenji Watanabe | Summary: Trions are a three-particle bound state of electrons and holes. Experimental realization of a trion liquid in the degenerate quantum limit would open a wide range of phenomena in quantum many-body physics. However, trions […]

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 […]

Learning Subject-Aware Cropping by Outpainting Professional Photos

Kavli Affiliate: Matthew Fisher | First 5 Authors: James Hong, Lu Yuan, Michaël Gharbi, Matthew Fisher, Kayvon Fatahalian | Summary: How to frame (or crop) a photo often depends on the image subject and its context; e.g., a human portrait. Recent works have defined the subject-aware image cropping task as a nuanced and practical version […]
