Unconventional topological Hall effect in high-topological-number skyrmion crystals

By Rui Zhu and Weinan Liu
Skyrmions with the topological number \(Q\) equal an integer larger than 1 are called high-topological-number skyrmions or high-\(Q\) skyrmions. In this work, we theoretically study the topological Hall effect in square-lattice high-\(Q\) skyrmion crystals (SkX) with \(Q=2\) and \(Q=3\). As a result of the emergent magnetic field, Landau-level-like electronic band... Show more
