Spin photogalvanic effect in two-dimensional collinear antiferromagnets
Rui-Chun Xiao, Ding-Fu Shao, Yu-Hang Li +1
Spin photogalvanic effect (SPGE) is an efficient method to generate a spin current by photoexcitation in a contactless and ultra-fast way. In two-dimensional (2D) collinear antifer…
Electrical Detection of Ferroelectric-like Metals through Nonlinear Hall Effect
Rui-Chun Xiao, Ding-Fu Shao, Wenjuan Huang +1
Ferroelectric-like metals are a relatively rare class of materials that have ferroelectric-like distortion and metallic conductivity. LiOsO is the first demonstrated and the mo…
Non-local Chemical Potential Modulation in Topological Insulators Via Electric Field Driven Trapped Charge Migration
Yasen Hou, Rui Xiao, Senlei Li +2
Topological insulators (TIs) host unusual surface states with Dirac dispersion and helical spin texture and hold high potentials for novel applications in spintronics and quantum c…
Emergence of excitonic superfluid at topological-insulator surfaces
Yasen Hou, Rui Wang, Rui Xiao +11
Excitons are spin integer particles that are predicted to condense into a coherent quantum state at sufficiently low temperature, and exciton condensates can be realized at much hi…
Density-functional investigation of rhombohedral stacks of graphene: topological surface states, nonlinear dielectric response, and bulk limit
Ruijuan Xiao, F. Tasnádi, K. Koepernik +3
A DFT-based investigation of rhombohedral (ABC)-type graphene stacks in finite static electric fields is presented. Electronic band structures and field-induced charge densities ar…
CoIr-carbon complexes with magnetic anisotropies larger than 0.2 eV: a density-functional-theory prediction
Ruijuan Xiao, Michael D. Kuz'min, Klaus Koepernik +1
We report a density-functional study of the heteronuclear CoIr dimer adsorbed on benzene or graphene. In either case CoIr prefers an upright position above the center of a carbon h…
Prediction of huge magnetic anisotropies of transition-metal dimer-benzene complexes
Ruijuan Xiao, Daniel Fritsch, Michael D. Kuz'min +4
Based on numerically accurate density functional theory (DFT) calculations, we systematically investigate the ground-state structure and the spin and orbital magnetism including th…
Co dimers on hexagonal carbon rings proposed as subnanometer magnetic storage bits
Ruijuan Xiao, Daniel Fritsch, Michael D. Kuz'min +5
It is demonstrated by means of density functional and ab-initio quantum chemical calculations, that transition metal - carbon systems have the potential to enhance the presently ac…
