A Hall viscosity for skyrmion via magnon interaction
Bom Soo Kim
We identify a Hall viscosity term directly from the Dzyaloshinskii-Moriya interaction (DMI), that breaks parity symmetry, in the skyrmion motion of insulating magnets by time-avera…
Skyrmion vs. antiskyrmion Hall angles
Bom Soo Kim
We observe significant, 6.5 - 12%, differences between skyrmion and antiskyrmion Hall angles in existing experimental data. To account for them, the Thiele equation is generalized…
Generalizing Thiele Equation
Bom Soo Kim
We generalize the Thiele equation with a transverse velocity to the skyrmion motion described by the collective coordinate of magnetization vector. It is applied to investigate sig…
QFT Entanglement Entropy, 2D Fermion and Gauge Fields
Bom Soo Kim
Entanglement and the Rényi entropies for Dirac fermions on 2 dimensional torus in the presence of chemical potential, current source, and topological Wilson loop are unified in a s…
Modeling Hall viscosity in magnetic-skyrmion systems
Bom Soo Kim
Magnetic skyrmions are topologically stable objects that are made with a bunch of spins tightly arranged in a smooth fashion. Their topological nature provides unusual and complex…
Topical Review on Skyrmions and Hall Transport
Bom Soo Kim
We review recent progresses towards an understanding of the Skyrmion Hall transport in insulating as well as conducting materials. First, we consider a theoretical breakthrough bas…
