A semimetal is a material with a small energy overlap between the bottom of the conduction band and the top of the valence band, but they do not overlap...

Weyl semimetals are semimetals or metals whose quasiparticle excitation is the Weyl fermion, a particle that played a crucial role in quantum field theory...
