Long-lived topological time-crystalline order on a quantum processor

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Liang Xiang, Wenjie Jiang, Zehang Bao, Zixuan Song, Shibo Xu | Summary: Topologically ordered phases of matter elude Landau’s symmetry-breaking theory, featuring a variety of intriguing properties such as long-range entanglement and intrinsic robustness against local perturbations. Their extension to periodically driven systems gives rise to exotic […]

Hyperelastic swelling of stiff hydrogels

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Justin C. Burton, , , | Summary: Hydrogels are biphasic, swollen polymer networks where elastic deformation is coupled to nanoscale fluid flow. As a consequence, hydrogels can withstand large strains and exhibit nonlinear, hyperelastic properties. For low-modulus hydrogel and semiflexible biopolymer networks, previous studies have […]

The Orbital Geometries and Stellar Obliquities of Exoplanet-Hosting Multi-Star Systems

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Malena Rice, Konstantin Gerbig, Andrew Vanderburg, , | Summary: The current orbital geometries of exoplanet systems offer a fossilized record of the systems’ dynamical histories. A particularly rich set of dynamical mechanisms is available to exoplanets residing in multi-star systems, which may have their evolution shaped by […]

Optically Helicity-Dependent Orbital and Spin Dynamics in Two-Dimensional Ferromagnets

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Shuo Li, Ran Wang, Thomas Frauenheim, Junjie He, | Summary: Disentangling orbital (OAM) and spin (SAM) angular momenta in the ultrafast spin dynamics of two-dimensional (2D) ferromagnets on subfemtoseconds is a challenge in the field of ultrafast magnetism. Herein, we employed non-collinear spin version of real-time time-dependent […]

Inferring the redshift of more than 150 GRBs with a Machine Learning Ensemble model

Posted by dbos Stanford

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Maria Giovanna Dainotti, Elias Taira, Eric Wang, Elias Lehman, Aditya Narendra | Summary: Gamma-Ray Bursts (GRBs), due to their high luminosities are detected up to redshift 10, and thus have the potential to be vital cosmological probes of early processes in the universe. Fulfilling this potential requires […]
