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.

Master Students:


Past members:

Serguei Tchoumakov (postdoc)

Serguei worked 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. Currently he is working in the field of cyber security.


Miguel Ángel Sánchez Martínez (@Migueltweetit)

Miguel Ángel was a student from 2018 until November 2021. He 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. In his PhD thesis, he focused on exploring linear and non-linear optical properties of novel topological metals, establishing their experimental signatures. His thesis received the Springer Best Thesis award. Congratulations!

Sharareh Sayyad (postdoc)

Sharareh was a postdoc from 2019 to 2021 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. Currently she works at the Max Planck Institute of Light in Erlangen in the group of F. Kunst.


Suman Aich (visiting student)

Suman visited us in the spring of 2019. He is interested in the emergence of topology in non-hermitian Hamiltonians from a quantum field theory point of view. He is a visiting student from the Indian Institute of Technology-Banaras Hindu University (IIT-BHU). He is currently pursuing a PhD in U. Bloomington, Indiana.



Oscar Pozo (visiting student)

Oscar visited our group in January 2019 to work with us on understanding optical properties in topological states. He is currently a postdoc at DIPC in San Sebastián. His thesis, which included a work with us in Grenoble won the best thesis GEFES 2022 prize. Congratulations Oscar!
