A Weyl fermion is a theoretical and experimental quasiparticle found in Weyl semimetals that behaves like an electron but possesses no mass. Because they are massless, these fermions can travel through a crystal lattice at extremely high speeds without scattering backwards. This property makes them highly attractive for future low-power, high-speed quantum computing and advanced semiconductor devices.

The research team is growing tantalum arsenide crystals to study Weyl fermion mobility at room temperature.
