Deep sub-wavelength localization of light and sound in dielectric resonators

Posted by klaurent February 2, 2022Caltech

Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Alkim Bozkurt, Chaitali Joshi, 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 […]

Active entanglement enables stochastic, topological grasping

Posted by dbos February 1, 2022Harvard

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 […]

An Optimally-Tuned Starting Point for Single-Shot $GW$ Calculations of Solids

Posted by February 1, 2022Berkeley

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 […]

Topological Graph-based Analysis of Solid-State Ion Migration

Posted by klaurent February 1, 2022Berkeley

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 […]

Rapid discovery of cathodes, ionic conductors and solid-state electrolytes through topological migration analysis

Posted by February 1, 2022Berkeley

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 […]
