Comment on "Coulomb Instabilities of a Three-Dimensional Higher-Order Topological Insulator"
Yu-Wen Lee, Min-Fong Yang
Based on renormalization-group (RG) calculations, a recent Letter by Zhao et al [Phys. Rev. Lett. 127, 176601 (2021)] claimed that three-dimensional second-order topological insula…
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…
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…
On the nature of the magnetic phase transition in a Weyl semimetal
Yu-Li Lee, Yu-Wen Lee
We investigate the nature of the magnetic phase transition induced by the short-ranged electron-electron interactions in a Weyl semimetal by using the perturbative renormalization-…
