Venue: 3.21 Berry Lecture Theatre, HH Wills Physics Labs Building, Tyndall Ave, 3pm

We would like to invite you to attend the Physics Colloquium, which will be held at 3pm on Mondays in 3.21, the Berry Lecture Theatre. The colloquia will be followed by tea and coffee in the staff coffee room. We hope to see you there!

The most imminent event in the series, on the 13th of February, will be presented by Antoine Georges (Collège de France and Flatiron Institute). Click here for a PDF of the abstract: Colloquium Poster 13th February 2023 (PDF, 496kB)

Abstract:

From copper-oxide superconductors to twisted two-dimensional materials, strong electronic correlations have focused enormous attention over several decades.

The classic paradigm of solid-state physics in which electrons form a gas of wave-like quasiparticles must be seriously revised for strongly correlated materials. Instead, a description accounting for both atomic-like excitations in real-space and quasiparticle excitations in momentum space is required.

I will review how Dynamical Mean-Field Theory (DMFT) fulfills this goal and provides an original physical perspective on strongly correlated electron materials as well as an efficient computational framework to understand and predict their properties. Thanks to the efforts of a whole community over almost three decades, the theory has been developed to such a point that it can successfully be applied to real materials, taking into account their structure and chemical composition. I will also outline how the theory is being extended and generalized in many fruitful directions.
