Chiral charge pumping in graphene deposited on a magnetic insulator
Michael Evelt, Hector Ochoa, Oleksandr Dzyapko +7
We demonstrate that a sizable chiral charge pumping can be achieved at room temperature in graphene/Yttrium Iron Garnet (YIG) bilayer systems. The effect, which cannot be attribute…
Emergent gauge fields from curvature in single layers of transition-metal dichalcogenides
Hector Ochoa, Ricardo Zarzuela, Yaroslav Tserkovnyak
We analyze the electron dynamics in corrugated layers of transition-metal dichalcogenides. Due to the strong spin-orbit coupling, the intrinsic (Gaussian) curvature leads to an eme…
Topological spin-transfer drag driven by skyrmion diffusion
Hector Ochoa, Se Kwon Kim, Yaroslav Tserkovnyak
We study the spin-transfer drag mediated by the Brownian motion of skyrmions. The essential idea is illustrated in a two-terminal geometry, in which a thin film of a magnetic insul…
A Realization of the Haldane-Kane-Mele Model in a System of Localized Spins
Se Kwon Kim, Héctor Ochoa, Ricardo Zarzuela +1
We theoretically study a spin Hamiltonian for spin-orbit-coupled ferromagnets on the honeycomb lattice. We find that the effective Hamiltonian for magnons, a quanta of spin-wave ex…
