Andreev reflection mediated by topological corner states in a two-dimensional honeycomb lattice
Kai-Tong Wang, Yunjin Yu, Fuming Xu +1
Topological corner states in two-dimensional second-order topological insulators (SOTIs) are localized in real space. We numerically demonstrate that such localized topological cor…
Linear thermal noise induced by Berry curvature dipole in a four-terminal system
Wenyu Chen, Miaomiao Wei, Yunjin Yu +2
In this work, we numerically investigate linear thermal noise in a four-terminal system with a finite Berry curvature dipole (BCD) using the nonequilibrium Green's function formali…
Realization of valley-spin polarized current via parametric pump in monolayer
Kai-Tong Wang, Hui Wang, Fuming Xu +2
Monolayer is a typical valleytronic material with valley-spin locked valence bands. We numerically investigate the valley-spin polarized current in monolayer vi…
Transport features of topological corner states in honeycomb lattice with multihollow structure
Kai-Tong Wang, Fuming Xu, Bin Wang +2
Higher-order topological phase in 2-dimensional (2D) systems is characterized by in-gap corner states, which are hard to detect and utilize. We numerically investigate transport pr…
Nonlinear Hall effect induced by internal Coulomb interaction and phase relaxation process in a four-terminal system with time-reversal symmetry
Miaomiao Wei, Bin Wang, Yunjin Yu +2
We numerically investigate the second-order nonlinear Hall transport properties of a four-terminal system with time-reversal symmetry and broken inversion symmetry. Within the none…
Photoinduced valley-polarized current of layered MoS2 by electric tuning
Yunjin Yu, Yanfeng Zhou, Langhui Wan +4
A photoinduced current of a layered MoS2-based transistor is studied from first-principles. Under the illumination of circular polarized light, a valley-polarized current is genera…
Shot noise of spin current and spin transfer torque
Yunjin Yu, Hongxin Zhan, Langhui Wan +4
We report the theoretical investigation of noise spectrum of spin current and spin transfer torque for non-colinear spin polarized transport in a spin-valve device which consists o…
Excitonic energy transfer in light-harvesting complexes in purple bacteria
Jun Ye, Kewei Sun, Yang Zhao +3
Two distinct approaches, the Frenkel-Dirac time-dependent variation and the Haken-Strobl model, are adopted to study energy transfer dynamics in single-ring and double-ring light-h…
Electron transport through Al-ZnO-Al: an {\it ab initio} calculation
Zijiang Yang, Langhui Wan, Yunjin Yu +2
The electron transport properties of ZnO nano-wires coupled by two aluminium electrodes were studied by {\it ab initio} method based on non-equilibrium Green's function approach an…
