Low-loss Nb on Si superconducting resonators from a dual-use spintronics deposition chamber and with acid-free post-processing

Posted by dbos Cornell

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Maciej W. Olszewski, Jadrien T. Paustian, Tathagata Banerjee, Haoran Lu, Jorge L. Ramirez | Summary: Magnetic impurities are known to degrade superconductivity. For this reason, physical vapor deposition chambers that have previously been used for magnetic materials have generally been avoided for making high-quality superconducting resonator […]

Microscopic mechanisms of flexoelectricity in oxide membranes

Posted by dbos Cornell

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Harikrishnan KP, Varun Harbola, Jaehong Choi, Kevin J. Crust, Yu-Tsun Shao | Summary: Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materials that lack inversion symmetry. In contrast, the flexoelectric effect […]

A Modular Quantum Network Architecture for Integrating Network Scheduling with Local Program Execution

Posted by dbos Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Thomas R. Beauchamp, Hana Jirovská, Scarlett Gauthier, Stephanie Wehner, | Summary: We propose an architecture for scheduling network operations enabling the end-to-end generation of entanglement according to user demand. The main challenge solved by this architecture is to allow for the integration of a network schedule with […]

The Chicago Carnegie Hubble Program: Improving the Calibration of SNe Ia with JWST Measurements of the Tip of the Red Giant Branch

Posted by dbos Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Taylor J. Hoyt, In Sung Jang, Wendy L. Freedman, Barry F. Madore, Kayla A. Owens | Summary: We present distances to ten supernova (SN) host galaxies determined via the red giant branch tip (TRGB) using JWST/NIRCAM and the F115W, F356W, and F444W bandpasses. Our analysis, including […]

BlackTHUNDER strikes twice: rest-frame Balmer-line absorption and high Eddington accretion rate in a Little Red Dot at $z=7.04$

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Roberto Maiolino, Michele Perna, Hannah Uebler, Xihan Ji | Summary: JWST spectroscopy has revealed a population of compact objects at redshifts $z=2$-9 with `v’-shaped spectral energy distributions, broad permitted lines, and, often, hydrogen Balmer absorption. Among these `Little Red Dots’ (LRDs), Abell2744-QSO1 at $z=7.04$ has […]
