High-mobility inertial domain walls driven by spin-transfer torque in a ferrimagnetic spinel oxide
Mingxing Wu, Shilei Ding, Laura van Schie +8
Efficient electrical manipulation of domain walls is key to developing magnetic devices with fast switching capabilities and low energy consumption. Here we demonstrate Bloch-type…
Electric-current-assisted nucleation of zero-field hopfion rings
Xiaowen Chen, Dongsheng Song, Filipp N. Rybakov +9
Magnetic hopfions are three-dimensional topological solitons -- knotted, vortex-like spin configurations. In chiral magnets, hopfions can appear as isolated structures or they can…
Transport properties of the pseudospin-3/2 Dirac-Weyl fermions in the double-barrier-modulated two-dimensional system
Rui Zhu
In this work, we analytically solved the pseudospin-3/2 Dirac equation and investigated the electronic transport properties in the double-barrier modulated two-dimensional system.…
Interaction-Induced Higher-Order Topological Insulator via Floquet Engineering
Chun-Ping Su, Zhao-Fan Cai, Tao Liu
Higher-order topological insulators have attracted significant interest in both static single-particle and many-body lattice systems. While periodically driven (Floquet) higher-ord…
A parameter-free statistical model for two-dimensional carbon nanostructures
Chang-Chun He, Shao-Gang Xu, Jiarui Zeng +4
Energy degeneracy in physical systems may be induced by symmetries of the Hamiltonian, and the resonance of degeneracy states in carbon nanostructures can effectively enhance the s…
Embedded skyrmion bags in thin films of chiral magnets
Luyan Yang, Andrii S. Savchenko, Fengshan Zheng +5
Magnetic skyrmions are topologically nontrivial spin configurations that possess particle-like properties. Earlier research was mainly focused on a specific type of skyrmion with t…
