Class of fermionic quasiparticles

In condensed matter physics, semi-Dirac fermions are a class of quasiparticles that are fermionic with the unusual property that their energy dispersion relation changes from quadratic to linear dependent on their direction of motion. Their theoretical properties have been studied for some time.

Their first observation in a solid was in zirconium silicon sulfide (ZrSiS), a topological semi-metal, and was published in 2024.
