Nonlinear opto-magnetic signature of d-wave altermagnets
Lijun Yang, Long Liang
Altermagnetism, a recently discovered collinear magnetic order with net zero magnetization but exhibiting spin-splitting band structure, has attracted much research interest due to…
Interband optical conductivity in two-dimensional semi-Dirac bands tilting along the quadratic dispersion
Xin Chen, Jian-Tong Hou, Long Liang +4
Two-dimensional (2D) semi-Dirac materials feature a unique anisotropic band structure characterized by quadratic dispersion along one spatial direction and linear dispersion along…
Weyl-mediated Ruderman-Kittel-Kasuya-Yosida interaction revisited: imaginary-time formalism and finite temperature effects
Mengyao Zhou, Hao-Ran Chang, Lijun Yang +1
Noncentrosymmetric magnetic Weyl semimetals provide a platform for investigating the interplay among magnetism, inversion symmetry breaking, and topologically nontrivial Weyl fermi…
Current response to axial gauge fields in noncentrosymmetric magnetic Weyl semimetals
Long Liang
We investigate the electric current response to axial gauge fields in noncentrosymmetric magnetic Weyl semimetals. The absence of both time-reversal and inversion symmetries allows…
