General method for calculating transport properties of disordered mesoscopic systems based on the nonequilibrium Green's function formalism
Gaoyang Li, MiaoMiao Wei, Fuming Xu +1
Disorder scattering plays important roles in quantum transport as well as various Hall effects, including the second-order nonlinear Hall effect induced by Berry curvature dipole.…
Spin separation and filtering assisted by topological corner states in the Kekulé lattice
Kai-Tong Wang, Hui Wang, Shijie Liu +2
Higher-order topological corner states have been realized in two-dimensional Kekulé lattice, which can be further coupled with spin polarization through the implementation of local…
Classification of spin Hall effect in two-dimensional systems
Longjun Xiang, Fuming Xu, Luyang Wang +1
Physical properties such as the conductivity are usually classified according to the symmetry of the underlying system using Neumann's principle, which gives an upper bound for the…
Quantum nonlinear ac transport theory at low frequency
Lei Zhang, Fuming Xu, Jian Chen +2
Based on the nonequilibrium Green's function (NEGF), we develop a quantum nonlinear theory to study time-dependent ac transport properties in the low frequency and nonlinear bias v…
Bulk-boundary-transport correspondence of the second-order topological insulators
Yuxiong Long^§, Miaomiao Wei^§, Fuming Xu +1
The bulk-boundary correspondence of the second-order topological insulator (SOTI) has been well established, but a universal transport signature for open systems is still absent. F…
Unified framework of the microscopic Landau-Lifshitz-Gilbert equation and its application to Skyrmion dynamics
Fuming Xu, Gaoyang Li, Jian Chen +4
The Landau-Lifshitz-Gilbert (LLG) equation is widely used to describe magnetization dynamics. We develop a unified framework of the microscopic LLG equation based on the nonequilib…
