Stability and current-driven dynamics of mixed-topology bimeron clusters
Philippe Heymes, Thomas L. Schmidt, Vladyslav M. Kuchkin
In this work, we study bimerons (in-plane skyrmions) and their clusters composed of states with mixed topological indices. These clusters provide flexibility in controlling the sky…
Three-Dimensional Shankar Skyrmions in Frustrated Antiferromagnets
Vladyslav M. Kuchkin, Ricardo Rama-Eiroa, Carlos Saji +2
We formulate a continuum theory for three-dimensional (3D) Shankar skyrmions in frustrated chiral antiferromagnets (AFs) and derive the conditions for metastable finite-size $π_3(S…
Quantum Hopfion rings in the cluster mean-field approximation
Vladyslav M. Kuchkin, Thomas L. Schmidt
We study the quantum properties of two- and three-dimensional spin textures -- -skyrmions and hopfion rings -- within the cluster mean-field approximation (CMFA). By combining…
