Optical stop analysis
WebDavid Weiss Lab. Jan 2014 - May 20246 years 5 months. Penn State University. We do research with neutral atoms trapped in optical lattices. … WebThe paper presents a general framework for developing the analytical sensitivities of the STOP prediction using the Chain Rule. The paper focuses on solving for the sensitivities of the steady-state, conduction-only, problem, using discipline modeling tools (thermal, structural, and optical) to compute the terms in the STOP gradients.
