Scratch work calculating retarded greens functions


Alongside our experimental efforts, we develop, apply and explore new theoretical models to understand energy transport through disordered materials. We interrogate dynamics in both natural and artificial systems (plus the occasional Gedankenexperiment!) to isolate and test design principles of excitonic transport. We also explore new strategies to extract more information from nonlinear spectroscopic data including filtering, signal processing, and identifying new spectral signatures in our data.
