Kavli Affiliate: Jia Liu | First 5 Authors: Menglu Yu, Ye Tian, Bo Ji, Chuan Wu, Hridesh Rajan | Summary: Fueled by advances in distributed deep learning (DDL), recent years have witnessed a rapidly growing demand for resource-intensive distributed/parallel computing to process DDL computing jobs. To resolve network communication bottleneck and load balancing issues in […]
Kavli Affiliate: Mohammad Mirhosseini | Summary:Optomechanical crystals provide coupling between phonons and photons by confining them to commensurate wavelength-scale dimensions. We present a new concept for designing optomechanical crystals capable of achieving unprecedented coupling rates by confining optical and mechanical waves to deep sub-wavelength dimensions. Our design is based on a dielectric bowtie unit cell […]
Kavli Affiliate: Robert Wood | First 5 Authors: Kaitlyn Becker, Clark Teeple, Nicholas Charles, Yeonsu Jung, Daniel Baum | Summary: Grasping, in both biological and engineered mechanisms, can be highly sensitive to the gripper and object morphology, as well as perception, and motion planning. Here we circumvent the need for feedback or precise planning by […]

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Stephen E. Gant, Jonah B. Haber, Marina R. Filip, Francisca Sagredo, Dahvyd Wing | Summary: The dependence of ab initio many-body perturbation theory within the $GW$ approximation on the eigensystem used in calculating quasiparticle corrections limits this method’s predictive power. Here, we investigate the accuracy of […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Jimmy-Xuan Shen, Haoming Howard Li, Ann Rutt, Matthew K. Horton, Kristin A. Persson | Summary: To accelerate the development of novel ion-conducting materials, we present a general graph-theoretic analysis framework for ion migration in any crystalline structure. The nodes of the graph represent metastable sites of […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Jimmy-Xuan Shen, Haoming Howard Li, Ann C. Rutt, Matthew K. Horton, Kristin A. Persson | Summary: We present a graph-theoretic analysis framework for ion migration in solid-state materials. The nodes of the graph are the metastable sites of the cation and the edges are discrete migration […]
Kavli Affiliate: Catherine E. Grant | First 5 Authors: Eric D. Miller, Catherine E. Grant, Marshall W. Bautz, Silvano Molendi, Ralph Kraft | Summary: The Wide Field Imager (WFI) flying on Athena will usher in the next era of studying the hot and energetic Universe. WFI observations of faint, diffuse sources will be limited by […]
Kavli Affiliate: Christopher Burke | Summary:Astronomers do not have a complete picture of the effects of wide-binary companions (semimajor axes greater than 100 AU) on the formation and evolution of exoplanets. We investigate these effects using new data from Gaia EDR3 and the TESS mission to characterize wide-binary systems with transiting exoplanets. We identify a […]
Kavli Affiliate: Steven W. Allen | First 5 Authors: Xuejian Shen, Thejs Brinckmann, David Rapetti, Mark Vogelsberger, Adam Mantz | Summary: We perform cosmological zoom-in simulations of $19$ relaxed cluster-mass haloes with the inclusion of adiabatic gas within the cold dark matter (CDM) and self-interacting dark matter (SIDM) models. These clusters are selected as dynamically […]
