Our 2021 group picture! From left to right, top top bottom: Sergueï, Adolfo, Sharareh, Baptiste, Daniel and Quentin. You can find info on them, including Miguel-Ángel who is missing in the picture, by scrolling down.

Adolfo G. Grushin (@aggrushin)

I am affiliated with the Néel Institute in Grenoble where I hold a permanent CRCN research position. You can find a summary of my interests here. I focus on the understanding topological phases of matter, with and without strong electron-electron correlations either metallic or insulating.

You can find an updated list of publications on arXiv or Google scholar.

PhD students:

Miguel Ángel Sánchez Martínez (@Migueltweetit)

Miguel Ángel has a background in two seemingly disconnected aspects of physics: quantum field theory and transport phenomena at the nanoscale; these two sets of knowledge find its perfect union in the study of topological phases of matter. He is focused in exploring new connections between topological phases, their experimental realizations, and high-energy physics methods.

Sharareh Sayyad 

Sharareh is working on the dynamics of topological systems and non-hermitian Hamiltonians. Previously she held a postdoc position in U. Tokyo working with H. Aoki. She graduated from the University of Hamburg under the supervision of M. Eckstein at the Max Planck Institute for the Structure and Dynamics of Matter.

Serguei Tchoumakov 

Serguei is working on the theory of Weyl semimetal interfaces, and the effect that strain and inhomogeneous magnetization has on these materials. Previously he was a postdoc at U. Montreal working with William Witczak-Krempa. He did his PhD in Orsay under the supervision of Mark O. Goerbig.
