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 […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Yiwen Tang, Siyuan Chen, Mark J. Bowick, Dapeng Bi, | Summary: Biological tissues transform between solid-like and liquid-like states in many fundamental physiological events. Recent experimental observations further suggest that in two-dimensional epithelial tissues these solid-liquid transformations can happen via intermediate states akin to the intermediate […]
Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Shuqiu Wang, Niall Kennedy, Kazuhiro Fujita, Shin-ichi Uchida, Hiroshi Eisaki | Summary: The primordial ingredient of cuprate superconductivity is the CuO2 unit cell. Here, theoretical attention usually concentrates on the intra-atom Coulombic interactions dominating the 3d9 and 3d10 configurations of each copper ion. However, if […]

Here, theoretical attention usually concentrates on the intra-atom Coulombic interactions dominating the 3d^9 and 3d^10 configurations of each copper ion. However, if […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Bekari Gabritchidze, Jacob Kooi, Kieran A. Cleary, Austin J. Minnich | Summary: The anomalous current-voltage characteristics of cryogenic SiGe heterojunction bipolar transistors (HBTs) have been a topic of investigation for many years. Proposed explanations include quasiballistic transport of electrons across the base or […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Bekari Gabritchidze, Justin H. Chen, Jacob Kooi, Kieran A. Cleary | Summary: The deviations of cryogenic collector current-voltage characteristics of SiGe heterojunction bipolar transistors (HBTs) from ideal drift-diffusion theory have been a topic of investigation for many years. Recent work indicates that direct […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Tobias J. Looser, Francesco D’Eugenio, Roberto Maiolino, Joris Witstok, Lester Sandles | Summary: Local and low-redshift ($z$<$3$) galaxies are known to broadly follow a bimodal distribution: actively star forming galaxies with relatively stable star-formation rates, and passive systems. These two populations are connected by galaxies in relatively […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Mohammad Ali Gorji, Misao Sasaki, , , | Summary: Cosmological stochastic gravitational waves (GWs) induced by a spectator field are usually expected to have an amplitude very small compared with those generated by the curvature perturbation, or equivalently by a field dominating the universe. On the contrary […]
