Magnetic impurities in an altermagnetic metal
Yu-Li Lee
We study the physics of dilute magnetic impurities in a two-dimensional altermagnetic metal. For the single impurity case, although the spin degeneracy is broken in an altermagneti…
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…
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-…
