Matrix Completion: Enhancing the Measurement Efficiency in 2D Spectroscopy — •Matthias Kost — Department of Theoretical Physics, Ulm University, Germany

2D spectroscopy is an indispensable tool in various modern sciences like physics, biology, chemistry and medicine. In particular, it resolves useful information about the inner electronic and spatial structure of molecules in a sample. However, the gain of high resolution requires a large number of measurements, which is one of the central problems concerning measurement efficiency.

Matrix completion is a mathematical procedure, providing the ability to recover certain matrices from just a few of its entries. This talk demonstrates, how the application of such algorithms in the context of 2D spectroscopy leads to significantly less measurement effort. This enhancement may be a crucial step towards the feasibility of more complex 2D spectroscopy methods.
