Correlated second-order Dirac semimetals with Coulomb interactions
Yu-Wen Lee, Yu-Li Lee
We investigate the effects of long range Coulomb interactions on the low-temperature properties of a second-order Dirac semimetal in terms of the renormalization group. In contrast…
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…
Electrical transport through a quantum dot side-coupled to a topological superconductor
Yu-Li Lee
We propose to measure the differential conductance as a function of the bias for a quantum dot side-coupled to a topological superconductor to detect the existence of the c…
Ground state of graphite ribbons with zigzag edges
Yu-Li Lee, Yu-Wen Lee
We study the interaction effects on the ground state of nanographite ribbons with zigzag edges. Within the mean-field approximation, we found that there are two possible phases: th…
