Skyrmion Lattice in Two-Dimensional Chiral Magnet
Jung Hoon Han, Jiadong Zang, Zhihua Yang +2
We develop a theory of the magnetic field-induced formation of Skyrmion crystal state in chiral magnets in two spatial dimensions, motivated by the recent discovery of the Skyrmion…
Dynamics of magnetization on the topological surface
Takehito Yokoyama, Jiadong Zang, Naoto Nagaosa
We investigate theoretically the dynamics of magnetization coupled to the surface Dirac fermions of a three dimensional topological insulator, by deriving the Landau-Lifshitz-Gilbe…
Current Modulator based on Topological Insulator with Sliding Magnetic Superlattice
Motohiko Ezawa, Jiadong Zang
We study theoretically the surface of a topological insulator with a sliding magnetic superlattice coated above. By analyzing time-dependent Dirac equations, the dynamics of the ze…
Topological quantum phase transition in an S=2 spin chain
Jiadong Zang, Hong-Chen Jiang, Zheng-Yu Weng +1
We construct a model Hamiltonian for S = 2 spin chain, where a variable parameter is introduced. The edge spin is S = 1 for , and S = 3/2 for . Due to the topologic…
Monopole Current and Unconventional Hall Response on Topological Insulator
Jiadong Zang, Naoto Nagaosa
We study theoretically the charged current above a topological insulator (TI) separated by a ferromagnetic insulating layer. An unconventional Hall response occurs in the conductin…
