One-dimensional Dexter-type excitonic topological phase transition
Jianhua Zhu, Ji Chen, Wei Wu
Recently topogical excitons have attracted much attention. However, studies on the topological properties of excitons in one dimension are still rare. Here we have computed the Zak…
Spin Torque on Magnetic Textures Coupled to the Surface of a Three-Dimensional Topological Insulator
Ji Chen, Mansoor Bin Abdul Jalil, Seng Ghee Tan
We investigate theoretically the spin torque and magnetization dynamic in a thin ferromagnetic (FM) layer with spatially varying magnetization. The FM layer is deposited on the sur…
Spin torque due to non-uniform Rashba spin orbit effect
Ji Chen, Mansoor Bin Abdul Jalil, Seng Ghee Tan
Following the early theoretical descriptions of the spin-orbit-induced spin torque [S.G. Tan et al., arXiv:0705.3502 (2007); S.G.Tan et al., Ann. Phys.326, 207 (2011)], the first e…
