Spintronics Research Group Jaroslav Fabian

We are a theoretical Condensed Matter group at the University of Regensburg with a research focus on Spin(Elec)tronics phenomena in complex systems at the nanoscale.

Our current research activities comprise first-principles studies of twisted heterostructures based on van der Waals materials and 2D magnets (twistronics), together with spin and magnetic-exchange proximity effects, as well as spin-orbit torques and magnetization dynamics. Moreover, we explore charge and spin transport properties of superconducting magnetic tunnel junctions (superconducting spintronics) controlled by spin-orbit interactions or inhomogeneous magnetization, including the recently intensively investigated supercurrent diode effect.

Our Research Topics

Twisted Heterostructures

From first-principles calculations, we study the electronic, spin, optical, and magnetic properties of twisted heterostructures consisting of van der Waals materials and transition-metal dichalcogenides.
Proximity Effects

We explore spin-orbit and exchange coupling proximity effects in stacked heterostructures of two-dimensional materials – together with their tunability through gating – employing ab initio techniques.
Magnetization Dynamics

Applying fully-relativistic first-principles approaches, we describe current-induced spin-orbit torques in van der Waals magnets, which are at the heart of these materials' magnetization dynamics.
Superconducting Junctions

We investigate charge and spin transport phenomena in superconducting magnetic tunnel junctions, including the recently intensively investigated supercurrent diode effect.
