Magneto-chiral transport effects of skyrmions

In the course of the past decade skyrmions emerged as a new class of fascinating topological magnetic particles. At the same time, modelling of electron-skyrmion interaction, responsible for skyrmion transport and dynamics, faces fundamental difficulties in explaining the available data and treating transport effects and dynamics of skyrmion in strongly spin-orbit coupled, insulating, superconducting, and even in most elementary compounds. It is thus imperative for future progress in the area to develop a proper theory which is able to treat electronic effects in skyrmions in full, accounting properly for the entangled dynamical and topological nature of chiral solitons. Driven by our previous research on exchange interactions, current-induced spin torques and topological magneto-transport properties of spin textures, in this project we are aiming at the rigorous microscopic and ab-initio theory of magneto-transport properties and related dynamical effects in large-scale chiral magnetic textures. Specifically, we will (i) focus on the interplay between an applied electric field with exchange interactions and spin torques; (ii) uncover the transport properties of skyrmions with a particular focus on a novel family of chiral effects, (iii) reach into the dynamical regime of interactions, torques and transport of textures evolving in time. One of the main objectives of the project is the discovery of novel types of hybrid topologies due to interplay of real-space spin, electronic, and magnonic degrees of freedom in dynamical textures. Successful research in this direction is a strategic visionary goal of the project, which has the potential to change the scope of our perception of spin textures as topological particles, and bring the field of skyrmionics to a qualitatively new level with strong connections to the fields of topological materials, topological magnonics, open and driven quantum systems, and even string theory.
