G2Aero: A Python package for separable shape tensors

September 20, 2023
Author(s)
Olga Doronina, Zachary J. Grey, Andrew Glaws
G2Aero is a Python package for the design and deformation of discrete planar curves and tubular surfaces using a geometric data-driven approach. G2Aero utilizes a topology of product manifolds: the Grassmannian---the set of 2-dimensional subspaces in Rn--

High accuracy, high dynamic range optomechanical accelerometry enabled by dual comb spectroscopy

September 20, 2023
Author(s)
David Long, Jasper Stroud, Benjamin Reschovsky, Yiliang Bao, Feng Zhou, Thomas W. LeBrun, David Plusquellic, Jason Gorman, Sean Bresler
Cavity optomechanical sensors offer exceptional sensitivity but interrogating the cavity motion with high accuracy and dynamic range has proven to be challenging. Here we employ a dual optical frequency comb spectrometer to readout a cavity optomechanical
