Seminar: Extracting spectral functions from imaginary time data
🧑‍ Emanuel Gull
🕥 Wed 8 Oct 10:30am
🗺️ King's S7.06
The math of Nevanlinna theory combined with numerical methods from signal processing and control theory, to overcome the ill-posed nature of the analytical continuation problem.

📢 From semiclassical scaling to quantum breakdown, our analytic formula matches the Lifshitz metal-insulator transition in MoTe2/WSe2 experiments and predicts a universal critical resistance RL=2pi h/e^2.
