Topological Hall-like behavior of multidomain ferromagnets
Houssam Sabri, Benjamin E. Carlson, Sergey S. Pershoguba +1
We investigate the emergence of topological Hall-like (THE-like) signals in disordered multidomain ferromagnets. Non-monotonic behavior in Hall resistivity, commonly attributed to…
Inertia in skyrmions confined to one-dimensional geometries
Koichiro Takahashi, Sergey S. Pershoguba, Jiadong Zang
Magnetic skyrmions are conventionally attributed to having zero mass. In contrast, we show that skyrmions confined to one-dimensional geometries generically acquire mass (inertia)…
Experimental observation of one-dimensional motion of interstitial skyrmion in FeGe
Dongsheng Song, Weiwei Wang, Jie-Xiang Yu +11
The interplay between dimensionality and topology manifests in magnetism via both exotic texture morphology and novel dynamics. A free magnetic skyrmion exhibits the skyrmion Hall…
Hall Effect Induced by Topologically Trivial Target Skyrmions
Tan Dao, Sergey S. Pershoguba, Jiadong Zang
Electrons moving through a noncoplanar magnetic texture acquire a Berry phase, which can be described as an effective magnetic field. This effect is known as the topological Hall e…
Direct current in a stirred optical lattice
Sergey S. Pershoguba, Victor M. Yakovenko
We study how the energy dispersion of bosonic atoms loaded into an optical lattice becomes modified due to periodic circular stirring of the lattice to the second order in the stre…
Optical control of topological memory based on orbital magnetization
Sergey S. Pershoguba, Victor M. Yakovenko
Under suitable conditions, some twisted graphene multilayers and transition-metal dichalcogenides become Chern insulators, exhibiting the anomalous quantum Hall effect and orbital…
