Weyl semimetals
Weyl semimetals are advanced materials where electrons behave as if they are massless particles called Weyl fermions, arising from special points (Weyl nodes) in their electronic structure. These materials exhibit unique properties, such as high electrical conductivity and unusual surface states, because of their topologically protected electronic behaviors. The Weyl nodes act like monopoles of magnetic charge in momentum space, leading to phenomena like very high mobility of charge carriers and robust surface currents immune to imperfections. These features make Weyl semimetals promising for future electronic and quantum technologies.
