In Martin Luther University (MLU), Mertig’s group conducts basic research in the field of solid-state theory, focusing on the microscopic understanding of electronic, magnetic, and ferroelectric properties at the nanoscale. In recent years, Mertig’s group has developed extensive collaboration with Bibes at Laboratoire Albert Fert on spin and orbital transportat oxide interfaces. In OBELIX, MLU will lead WP1with JGU and will bring its expertise in relativistic and geometric effects for transversal transport coefficients based on spin- and orbital degrees of freedom in oxide heterostructures.
