ICTP Colloquium 24 February

ICTP is pleased to announce a colloquium by Ataç Imamoǧlu on the "Optical Investigation of Strongly Correlated Electrons". The talk will take place on Tuesday 24 February at 14:00 CET in ICTP’s Budinich Lecture Hall, Leonardo Building, and will be livestreamed on the ICTP Youtube channel.

Ataç Imamoǧlu is a professor at ETH Zurich, Switzerland, where he leads the Quantum Photonics group. His research focuses on using quantum optical techniques to study strongly correlated electrons in two dimensional materials.
After graduating from Middle East Technical University in Ankara, Turkey, he obtained a PhD from Stanford University. Between 1993 and 2002 he was a faculty member at UC Santa Barbara and has been a professor of physics at ETH Zurich since 2002.

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.
