You are most cordially invited to the ICTP Colloquium on "Optical Investigation of Strongly Correlated Electrons" by Prof. Atac Imamoglu, ETH Zurich, Switzerland.
The Colloquium will take place on Tuesday 24 February at
16:00 hrs CET, and live-streamed. Refreshments will be
served in the lobby of the Leonardo Building after the talk.
Biosketch:
Atac Imamoglu graduated from Middle East Technical University in Ankara, Turkey. In 1991, he obtained his PhD from Stanford University. Between 1993 and 2002 he was a faculty member at UC Santa Barbara. Since 2002, he is a professor of physics at ETH Zurich and leads the Quantum Photonics group. His research focuses on using quantum optical techniques to study strongly correlated electrons in two dimensional materials.
Abstract:
Two dimensional semiconductors subject to a moire potential provide a fertile ground for exploration of strongly correlated phases, ranging from kinetic magnetism, through fractional Chern insulators to unconventional superconductivity. In the first set of experiments , we studied topologically trivial moire bands with vanishing exchange interactions; here we observed ferromagnetic correlations stemming from a kinetic mechanism. The focus of the second set of experiments was on interplay between interactions and topology in twisted MoTe2 homobilayer. In this system, we demonstrated optical control of ferromagnetism in general and topological Chern insulator states in particular.For info, please check the following link: https://indico.ictp.it/event/11281/
