Thomas Naimer, Ph.D. student in our group, successfully defended his thesis entitled "Twist angle and proximiy spin-orbit coupling in graphene-based heterostructures: an ab-initio approach".

Congratulations, Thomas!

Dr. Paulo E. Faria Junior, Research Associate in our group, has completed his Habilitation process giving an exciting talk in front of the faculty members.

Paulo's groundbreaking research, combining first-principles with phenomenological methodologies, has significantly advanced our common understanding of exciton physics in two-dimensional materials and deciphered the impact of external stimuli such as electric or magnetic fields, strain, and twisting.

We are looking forward to Paulo's continued contributions to this exciting field!

Congratulations, Paulo!

With Prof. Dr. Jaroslav Fabian, Dr. Andreas Costa, Thomas Naimer, and Dr. Klaus Zollner, our team has shown a comprehensive presence at Graphene Week 2024 in Prague advertising our research on proximity and twisting effects in graphene/van-der-Waals heterostructures and the supercurrent diode effect in two-dimensional systems.

Dr. Lukas Cvitkovich joins our group as a PostDoc. Lukas will be working on first-principles descriptions?of magnetic tunnel junctions and large-scale systems.

Welcome, Lukas!

The latest issue of Europhysics News features a highlighted article authored by Prof. Dr. Jaroslav Fabian and Dr. Klaus Zollner to illustrate the unprecedented tunability of spin interactions in van-der-Waals heterostructures through, e.g., stacking and twisting individual layers. These properties make van-der-Waals heterostructures promising candidates for spintronics devices and next-generation information technologies.

The full article is available here.

Dr. Gusthavo Brizolla joins our group as a PostDoc. Gusthavo will be working on modeling spin-orbit torques in two-dimensional magnets from first-principles calculations.

Welcome, Gusthavo!

The award for the best poster presented at the International Conference on Internal Interfaces 2024 (IC II-24) in Marburg has been awarded to Dr. Klaus Zollner for his contribution on "Proximity-induced spin interactions in twisted van-der-Waals heterostructures".

Congratulations, Klaus!
