Prof. Dr. Olena Gomonay (Institute of Physics, JGU)

Project A11 addresses from theory the impact of current- and laser-driven lattice vibrations, magnonic excitations, and currents of angular momentum on non-linear AFM dynamics and AFM switching, thus bringing antiferromagnets into the realm of orbitronics. With our project we will advance the understanding of how lattice degrees of freedom in combination with novel types of currents of angular momentum can improve the switching properties of antiferromagnetic order, and result in novel types of non-linear AFM dynamics.

A11  Spin+Optics: Theoretical design of antiferromagnetic optospintronics

Prof. Dr. Juriy Mokrousov (Institute of Physics, JGU)
Prof. Dr. Olena Gomonay (Institute of Physics, JGU)

The overall goal of project A11 is the theoretical understanding, discovery and design of novel fundamental spin phenomena in the field of antiferromagnetic (AFM) optospintronics. We will use  highly-predictive microscopic and ab initio theory in combination with non-linear magnetization dynamics simulations to shed light on the complex processes which accompany the interaction of optical pulses with the staggered or non-collinear order. Providing an insight into the phenomena of optically-induced effective magnetic fields, spin and orbital polarization, and corresponding dynamics of the sublattice magnetization in various AFMs, we aim to significantly advance our understanding of the interaction of AFMs with light by optimizing the conditions for the ultrafast and energy-efficient optically-induced switching of the AFM magnetization in complex transition-metal systems.
