Berry curvature induced anisotropic magnetotransport in a quadratic triple-component fermionic system
Berry curvature induced anisotropic magnetotransport in a quadratic triple-component fermionic system
Triple-component fermions (TCFs) are pseudospin-1 quasiparticles hosted by certain three-band semimetals in the vicinity of their band-touching nodes (2019Phys. Rev.B100235201). The excitations comprise of a flat band and two dispersive bands. The energies of the dispersive bands areE±=±αn2k⊥2n+vz2kz2withk⊥=kx2+ky2andn= 1, 2, 3. In this work, we obtain the exact expression of …
