Condensed-Matter Physics & Materials Science Seminar

"Quasiparticle spectra from stochastic many-body methods"

Presented by Vojtech Vlcek, University of California, Los Angeles

Thursday, November 9, 2017, 1:30 pm — ISB Bldg. 734 Conf. Rm. 201 (upstairs)

I will present new developments and applications of stochastic approaches to electronic structure and many-body perturbation theory, which overcome the steep scaling of conventional deterministic schemes. The general principles of linear-scaling stochastic methods for TDDFT, GW and BSE will be discussed and exemplified on realistic nanoscale systems with more than 5000 valence electrons. The stochastic approaches enable mapping the evolution of optical absorption, spectral functions and quasiparticle energies and lifetimes, as well as the emergence of collective excitations, over the full range from molecules to large bulk-like 3D nanoclusters and 2D layers.
