- Description
- In this first part, I would like to discuss the effects of strong magnetic impurities on the edge transport of a quantum spin Hall insulator. The location of the impurity strongly influences its effects. When it is near to the edge of the system, antiresonance of the transmission for the edge states happens. The interaction effects will be also discussed based on the renormalization theory. In the second part, I will discuss transport properties and topological phase transition in 2D interacting disordered Chern insulator within the dynamical mean-field theory. The band inversion induced by the disorder and interaction and the delocalization effects induced by interaction are discussed. We found that the repulsive onsite interaction is really friendly to the topological phase in the disordered Chern insulator
