Magnetic impurity in a triple-component semimetal
Yu-Li Lee, Yu-Wen Lee
We investigate the effects of a magnetic impurity in a multiband touching fermion system, specifically, a triple-component semimetal with a flat band, which can be realized in a fa…
The phase diagram of a two-dimensional dirty tilted Dirac semimetal
Yu-Li Lee, Yu-Wen Lee
We investigate the effects of quenched disorder on a non-interacting tilted Dirac semimetal in two dimensions. Depending on the magnitude of the tilting parameter, the system can h…
On the renormalization of Coulomb interactions in two-dimensional tilted Dirac fermions
Yu-Wen Lee, Yu-Li Lee
We investigate the effects of long-ranged Coulomb interactions in a tilted Dirac semimetal in two dimensions by using the perturbative renormalization-group method. Depending on th…
Electrical control and interaction effects of the RKKY interaction in helical liquids
Yu-Wen Lee, Yu-Li Lee
We study the RKKY interaction mediated by the helical edge states of a quantum spin Hall insulator in the presence of the Rashba spin-orbital coupling induced by an external electr…
