Faux particles commit physics faux pas
Quasiparticle known as type-II Weyl fermion violates Lorentz symmetry
WEYL STYLE In solids, groups of particles can act in concert, behaving like a single, fundamental type of particle, known as a fermion. One such type of quasiparticle, called a type-II Weyl fermion, breaks a fundamental rule of physics called Lorentz symmetry.
