Summary
Weyl Points
are
Topologically protected points
in the
Momentum Space
of certain crystals, where the
Energy of the quasiparticles
(akin to the electrons) linearly depends on the momentum around these points, leading to exotic phenomena like
Fermi Arcs
and
Anomalous Hall effects
. They serve as
Monopoles of Berry curvature
in a
Three-dimensional Brillouin zone
, significantly influencing the
Electronic Properties
and leading to robust,
Gapless states
at their location.
