Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Michael M. Fausnaugh, Rahul Jayaraman, Roland Vanderspek, George R. Ricker, Christopher J. Burke | Summary: We present the TESS light curve of GRB 230307A. We find two distinct components: a bright, prompt optical component at the time of the Fermi observation that peaked at TESS magnitude […]
Kavli Affiliate: Paul Alivisatos | First 5 Authors: Alexander Pattison, Cassio C. S. Pedroso, Bruce E. Cohen, Justin C. Ondry, A. Paul Alivisatos | Summary: Scanning transmission electron microscopy is a common tool used to study the atomic structure of materials. It is an inherently multimodal tool allowing for the simultaneous acquisition of multiple information […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Kai Wang, Jianyang Gu, Daquan Zhou, Zheng Zhu, Wei Jiang | Summary: Dataset distillation reduces the network training cost by synthesizing small and informative datasets from large-scale ones. Despite the success of the recent dataset distillation algorithms, three drawbacks still limit their wider application: i). the synthetic […]
Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Ady Stern, Anton Akhmerov, , | Summary: Orbital diamagnetism requires closed orbits according to the Liftshiftz-Kosevich theory. Therefore, one might expect that open Fermi surfaces do not have a diamagnetic response. Contrary to this expectation, we show that open orbits in finite systems do contribute […]
Kavli Affiliate: Srijit Goswami | First 5 Authors: Christian G. Prosko, Ivan Kulesh, Michael Chan, Lin Han, Di Xiao | Summary: A single electron shared between two levels threaded by a magnetic flux is an irreducibly simple quantum system in which interference is predicted to occur. We demonstrate tuning of the tunnel coupling between two […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Merritt P. Losert, M. A. Eriksson, Robert Joynt, Rajib Rahman, Giordano Scappucci | Summary: Silicon/silicon-germanium heterostructures have many important advantages for hosting spin qubits. However, controlling the valley splitting (the energy splitting between the two low-lying conduction-band valleys) remains a critical challenge for ensuring qubit reliability. Broad […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: M. F. Albakry, I. Alkhatib, D. Alonso, D. W. P. Amaral, P. An | Summary: We measured the nuclear–recoil ionization yield in silicon with a cryogenic phonon-sensitive gram-scale detector. Neutrons from a mono-energetic beam scatter off of the silicon nuclei at angles corresponding to energy depositions […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Kota Fukuzawa, Takeo Kato, Mamoru Matsuo, Thibaut Jonckheere, Jérôme Rech | Summary: We theoretically study spin pumping from a ferromagnetic insulator (FI) into a carbon nanotube (CNT). By employing the bosonization method, we formulate the Gilbert damping induced by the FI/CNT junction, which can be measured by […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Alexandra Veledina, Fabio Muleri, Juri Poutanen, Jakub Podgorný, Michal Dovčiak | Summary: The accretion of matter by compact objects can be inhibited by radiation pressure if the luminosity exceeds the critical value, known as the Eddington limit. Discovery of ultraluminous X-ray sources has shown that accretion […]
