Group news as we start 2024

After a long time without updates, there have been several changes in the group during the last year. Starting with the most recent, Daniel Muñoz Segovia just graduated before the Christmas break and has started a postdoc at Columbia University in the group of Raquel Queiroz. Congratulations Dani, and all the best! 

In 2023 Miguel Angel Sanchez Martinez also left us for a postdoctoral position at the University of Bristol with Felix Flicker, and Helene Muller also switched PhD to the University of Wurzburg, now advised by Viktoriia Kornich. Good luck to both too! 

Finally, since May 2023 we also have a new addition to the group. Fernando Peñaranda joins us after a PhD at ICMM in Madrid, to work on twisted heterostructures and nonlinear optics. Welcome Fernando!

Oscar Pozo defends his PhD thesis

Óscar Pozo Ocaña defended his PhD thesis “On symmetry and topological aspects of novel phases of matter” on Dec. 21st 2021. His thesis was co-advised with Maria Vozmediano from Instituto de Ciencia de Materiales de Madrid (ICMM), and is officially the first PhD from our group. Óscar will now start a postdoc at the Centro de Física de Materiales (CFM) in San Sebastian. Congratulations Oscar and all the best in your career!

Experimental collaboration on photocurrents in CoSi is published!

Working in collaboration with the Wu lab from U. Penn and several theory groups, we have shown that measurements of the circular photogalvanic effect (CPGE) in CoSi, a topological semimetal, are consistent with theory and prove that the observation of the quantized CPGE measuring the topological charge of a node should be feasible with the right material tuning. Congrats to Oscar who did great work leading the effective model calculations! And as usual in close collaboration with Adolfo Gruhsin too. Check out the paper published in Nature Communications!
