Participant 2 – RUB

Ruhr-University Bochum

The Ruhr-University Bochum (RUB) is one of the largest public universities in Germany. The RUB is the university renowned on the international scale by the fundamental research in material science and quantum physics, as well as multidisciplinary applied research in modern quantum electronics. The RUB group of the project is a part of Institut für Theoretische Physics III (TP III) of the RUB. The researchers of TP III have obtained over the last decades a large number of fundamental scientific results in the field of superconductivity, quantum many body theory, quantum physics of low-dimensional systems, e.g. graphene, topological insulators.

Researchers involved in the SUPERGALAX project

The RUB partner group (Prof. Ilya Eremin (PI) and Dr. Mikhail Fistul) has a long established expertise in a theoretical study of coherent quantum phenomena in various metallic, magnetic, semiconducting and superconducting nanostructures under equilibrium or non-equilibrium conditions. Last several years the RUB group has also concentrated on the number of projects related to the analysis of the proximity effects in heterostructures containing magnets and superconductors, analyzed the properties of unconventional superconductors, studied unconventional methods of quantum computing, i.e. Majorana fermions or skyrmions.

Prof. Dr. Ilya M. Eremin (Gender male), was born in 1974 in Kazan, Russia. In 1996 he was graduated in Physics from the Kazan University, Russia. After obtaining his Ph.D. in Russian Federation at one of the leading universities Kazan Federal (State) University in 1999 in the area of Theoretical and Mathematical Physics, he moved to Germany first as Alexander von Humboldt fellow with Karl Bennemann from the Free University of Berlin and later as a long-term post-doctoral research associate (Wi.Mi.) in the group of Felix von Oppen. In February 2005 he joined the Max-Planck Institute for Physics of Complex Systems in Dresden (joint offer with TU Braunschweig) as a junior-professor. In April 2010 he was appointed as a W2 Professor (tenured Associate Professor) in Theoretical Physics (Condensed Matter theory) at the Ruhr-Universität Bochum. In January 2020 he was promoted to the full (chair) professorship in Condensed Matter Theory at the Ruhr-Universität Bochum.

The main scientific interests lie in the field of quantum many-body effects in application to solid state systems both analytically and numerically. To be more precise he is interested in the theoretical investigation of collective effects in novel materials like strongly correlated low-dimensional electronic, topologically non-trivial and magnetic systems. It includes unconventional superconductivity phenomena, exotic collective excitations in geometrically frustrated systems and their topological properties, and application of these effects for novel spintronics quantum computing devices as well as the effects out of equilibrium. In his research, he is using modern methods of theoretical physics, ranging from numerically based modeling including the electronic corrections, and density matrix approaches for non-equilibrium systems as well as more analytical quantum field theory methods for effective theories including the renormalization group and exactly solvable models.

Overall, he published more than 150 research papers in the refereed journals such as Physical Review B, Physical Review Letters, Nature, Nature Communications, Nature Physics, New Journal of Physics, Europhysics Letters and so on. He has established the research group at Ruhr-University in Bochum. Presently he is supervising several Ph.D. students (Dipl.-Phys. Jakob Böker, started Autumn 2016, Dipl.-Phys. Dustin Altenfeld, started in 2014, Dipl. Phys. Fabian Lambert, started in 2015, Dipl.-Phys. Marvin Müller, started in 2017, Samme Dahir, started in 2018), and several Bachelor and Master students. His current h-index is 39 (Google Scholar), 31 (WoS).

Dr. Mikhail V. Fistul (Gender male), was born in 1959 in Moscow, Russia. In 1981 he was graduated from the Department of Theoretical Physics of Moscow Steel and Alloys Institute (MISiS). In 1984 Dr. Mikhail Fistul has received his Ph.D. in Physical and Mathematical Sciences from the MISIS, Russia. His scientific adviser was prominent Russian physicist Prof. Lev Aslamazov. In 1984-1991 Mikhail Fistul kept various research positions (Junior Researcher, Senior Researcher) at MISIS. From 1991-1997 he worked as the Research Associate at Purdue University, IN USA. In 1998-2000 he worked at the University Erlangen- Nürnberg as the recipient of the Alexander von Humboldt Research Fellowship. Up to now Dr. Mikhail Fistul kept various research/teaching positions: 2000-2002-Research Associate, Max-Planck Institute for Physics of Complex Systems, Dresden; 2002-2004- Visiting Professor, University Erlangen-Nürnberg, Erlangen Germany; 2004-2016- Researcher, Ruhr University Bochum, Bochum (Germany), 2017- Research Fellow, Center for Theoretical Physics of Complex Systems, Institute for Basic Science (IBS), Daejeon, Republic of Korea.

In January 2019 Mikhail Fistul was appointed as a Professor in NanoScience at the University of Science and Technology, Daejeon, Republic of Korea. Mikhail Fistul has published more than 110 papers in leading scientific journals, i.e. Nature (2), Nature Communications (3), ASC Nano (1), Physical Review Letters (9), etc., his h-index is 26 (Google Scholar), 23 (WoS). He has given more than 80 talks on various international conferences, workshops and seminars. Mikhail Fistul was a scientific organizer of an international workshop “Quantum effects in systems of nanocrystals (QEAN)” at the Lorenz Center, Netherlands. He serves for many years as a referee for top physical journals, i.e. Physical Review Letters, Physical Review B(E), Journal of Physics, etc.

During his scientific carrier Dr. Mikhail Fistul taught the advanced courses at University Erlangen-Nuernberg (Erlangen,Germany), NUST MISiS (Moscow, Russia), IBS PCS Daejeon (South Korea), namely, Physics of Superconductors, Quantum phenomena in mesoscopic solid-state systems, Introduction in solid state quantum computing, Spintronics, Physical principles of quantum information and macroscopic quantum phenomena, Superconducting circuits and qubits.
