Functional Nanoscale Structure Probe and Simulation Laboratory (Funsilab)
We are interested in investigating physical phenomena across several length scales, i.e. from adatoms to large non-collinear spin-textures such as magnetic skyrmions, involving the interplay of spin, orbital, charge degrees of freedom, which defines the field of spin-orbitronics.
We develop theoretical concepts and methods based on density functional theory (DFT), time-dependent DFT and many-body perturbation theory. We investigate electronic, magnetic and transport properties with a particular focus on dynamical effects, paramount in information and communication technology and essential in any reading and writing processes involving magnetic bits of information.
From a first-principles perspective, not much is known about the dynamical behaviour of complex magnetic materials in reduced dimensionality and their signature in the AC transport regime. Magnetic bits can be the building blocks or matter, such as adatoms and clusters deposited on surfaces, or much larger objects such as magnetic skyrmions, which are topological entities linking the so-called spintronics to topotronics.
