Kavli Affiliate: Katja C. Nowack | Summary:We use scanning superconducting quantum interference device (SQUID) microscopy to image vortices in superconducting strips fabricated from NbTiN thin films. We repeatedly cool superconducting strips with different width in an applied magnetic field and image the individual vortices. From these images we determine the threshold field at which the […]
Kavli Affiliate: Katja C. Nowack | Summary:We use scanning superconducting quantum interference device (SQUID) microscopy to image individual vortices in superconducting strips fabricated from NbTiN thin films. By repeatedly field-cooling strips of different widths in applied magnetic fields, we extract the threshold field at which the first vortex enters a strip, as well as the […]
Kavli Affiliate: Gregory D. Fuchs | 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 devices. In this article, we show by example that such chambers can be used for this purpose; with […]
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 […]
Kavli Affiliate: Gregory D. Fuchs | 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 couples strain gradients to electric polarization, and is a universal property in insulating materials of arbitrary […]
Kavli Affiliate: Kyle Shen | First 5 Authors: Ping-Yen Shen, Ping-Yen Shen, , , | Summary: Solar sails enable propellant-free space missions by utilizing solar radiation pressure as thrust. However, disturbance torques act on the solar sail and effective attitude control leads to the continuous accumulation of reaction wheel angular momentum, necessitating an efficient momentum […]
Kavli Affiliate: Jie Shan | First 5 Authors: Yin Chen, Yin Chen, , , | Summary: This article explores the structure theory of compatible generalized derivations of finite-dimensional $ω$-Lie algebras over a field $mathbbK$. We prove that any compatible quasiderivation of an $ω$-Lie algebra can be embedded as a compatible derivation into a larger $ω$-Lie […]
Kavli Affiliate: Christopher Ober| First 5 Authors: Matthias Mayr, Matthias Mayr, , , | Summary:Trilinos is a community-developed, open-source software framework that facilitates building large-scale, complex, multiscale, multiphysics simulation code bases for scientific and engineering problems. Since the Trilinos framework has undergone substantial changes to support new applications and new hardware architectures, this document is […]
Kavli Affiliate: Nicholas L. Abbott| First 5 Authors: Robert Besuner, Robert Besuner, , , | Summary:The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be our only hope to unravel these long-standing mysteries. In this white paper, we […]
Kavli Affiliate: Dan Luo | First 5 Authors: Kexin Li, Kexin Li, , , | Summary: Biomedical research increasingly relies on heterogeneous, high-dimensional datasets, yet effective visualization remains hindered by fragmented code resources, steep programming barriers, and limited domain-specific guidance. Bizard is an open-source visualization code repository engineered to streamline data analysis in biomedical research. […]
