Vibration characteristics of a continuously rotating superconducting magnetic bearing and potential influence to TES and SQUID

Posted by klaurent October 21, 2022Tokyo

Kavli Affiliate: Tomotake Matsumura | Summary:We measured the vibration of a prototype superconducting magnetic bearing (SMB) operating at liquid nitrogen temperature. This prototype system was designed as a breadboard model for LiteBIRD low-frequency telescope (LFT) polarization modulator unit. We set an upper limit of the vibration amplitude at $36~mathrmμm$ at the rotational synchronous frequency. During […]

The connection between galactic outflows and the escape of ionizing photons

Posted by klaurent October 20, 2022November 1, 2022Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Ramesh Mainali, Jane R. Rigby, John Chisholm, Matthew Bayliss, Rongmon Bordoloi | Summary: We analyze spectra of a gravitationally lensed galaxy, known as the Sunburst Arc, that is leaking ionizing photons, also known as the Lyman continuum (LyC). Magnification from gravitational lensing permits the galaxy to […]

Coherence requirements for quantum communication from hybrid circuit dynamics

Posted by klaurent October 20, 2022UCSB

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Shane P. Kelly, Ulrich Poschinger, Ferdinand Schmidt-Kaler, Matthew P. A. Fisher, Jamir Marino | Summary: The coherent superposition of quantum states is an important resource for quantum information processing which distinguishes quantum dynamics and information from their classical counterparts. In this article we determine the […]

Strong variation of spin-orbit torques with relative spin relaxation rates in ferrimagnets

Posted by klaurent October 20, 2022Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Lijun Zhu, Daniel C Ralph, , , | Summary: Spin-orbit torques (SOTs) have been widely understood as an interfacial transfer of spin that is independent of the bulk properties of the magnetic layer. Here, we report that SOTs acting on ferrimagnetic FexTb1-x layers decrease and vanish […]
