Measuring gravity with milligram levitated masses
Tim M. Fuchs, Dennis G. Uitenbroek, Jaimy Plugge +5
Gravity differs from all other known fundamental forces since it is best described as a curvature of spacetime. For that reason it remains resistant to unifications with quantum th…

Proof methods for robust low-rank matrix recovery
Tim Fuchs, David Gross, Peter Jung +3
Low-rank matrix recovery problems arise naturally as mathematical formulations of various inverse problems, such as matrix completion, blind deconvolution, and phase retrieval. Ove…

Sketching with Kerdock's crayons: Fast sparsifying transforms for arbitrary linear maps
Tim Fuchs, David Gross, Felix Krahmer +2
Given an arbitrary matrix , we consider the fundamental problem of computing for any such that is -sparse. While fast al…
