Magnetic correlation between two local spins in a quantum spin Hall insulator
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
Two spins located at the edge of a quantum spin Hall insulator may interact with each other via indirect spin-exchange interaction mediated by the helical edge states, namely the R…
An Anderson impurity interacting with the helical edge states in a quantum spin Hall insulator
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
Using the natural orbitals renormalization group (NORG) method, we have investigated the screening of the local spin of an Anderson impurity interacting with the helical edge state…
Order parameter for the multichannel Kondo model at quantum criticality
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
A multichannel Kondo model, where two or more equivalent but independent channels of electrons compete to screen a spin-1/2 impurity, shows overcompensation of the impurity spin, l…
Strain-mediated Symmetry Breaking Switch with Perpendicular Magnetic Anisotropy
Ruoda Zheng, Jin-Zhao Hu, Qianchang Wang +3
Magnetic switch with perpendicular magnetic anisotropy (PMA) is a promising method for controlling magnetization in several applications like magnetic tunnel junction and magnetic…
