Realistic Runtime Analysis for Quantum Simplex Computation

Kavli Affiliate: David Gross | First 5 Authors: Sabrina Ammann, Maximilian Hess, Debora Ramacciotti, Sándor P. Fekete, Paulina L. A. Goedicke | Summary: In recent years, strong expectations have been raised for the possible power of quantum computing for solving difficult optimization problems, based on theoretical, asymptotic worst-case bounds. Can we expect this to have […]

Dynamic modeling of wing-assisted inclined running with a morphing multi-modal robot

Kavli Affiliate: Morteza Gharib | First 5 Authors: Eric Sihite, Alireza Ramezani, Morteza Gharib, , | Summary: Robot designs can take many inspirations from nature, where there are many examples of highly resilient and fault-tolerant locomotion strategies to navigate complex terrains by using multi-functional appendages. For example, Chukar and Hoatzin birds can repurpose their wings […]

Converting Non-Equilibrium Charge Density into Spin Current

Kavli Affiliate: Joel E. Moore | First 5 Authors: Marc Vila, Joel E. Moore, , , | Summary: The interconversion between charge and spin degrees of freedom is of both fundamental and technological relevance in spintronics. While a non-equilibrium spin density and a charge current are related by the well known Rashba-Edelstein effect, here we […]

Causality-Informed Data-Driven Predictive Control

Kavli Affiliate: Biao Huang | First 5 Authors: Malika Sader, Yibo Wang, Dexian Huang, Chao Shang, Biao Huang | Summary: As a useful and efficient alternative to generic model-based control scheme, data-driven predictive control is subject to bias-variance trade-off and is known to not perform desirably in face of uncertainty. Through the connection between direct […]

Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals

Kavli Affiliate: Joshua Frieman | First 5 Authors: Chin Yi Tan, Anowar J. Shajib, Simon Birrer, Alessandro Sonnenfeld, Tommaso Treu | Summary: The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The power-law assumption for the radial mass profile in ellipticals […]
