Welcome to the website of the Working group / Arbeitsgruppe (AG) Theory of Spin Systems.
We are theoretical solid-state physicists with a keen interest in the spin degree of freedom. Please see our Research page for further details. We enjoy working with colleagues, both at the RPTU and internationally. Our theoretical projects keep a close eye on experimental feasibility and advancements.
We also take great pride and joy in educating students. This includes teaching courses, supervising research projects and theses, as well as guiding students in developing leadership skills. See the Teaching page.
We are always happy to welcome new group members who share our enthusiasm towards learning, self-development, and contributing to the development of people and institutions around us. Please write to Prof. Kamra if you would like to join us.
