A charge-density wave (CDW) is an ordered state that breaks translational symmetry and is characterized by a modulation in the electronic charge density as well as a corresponding … A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two … See more The helicity of a particle is positive (“right-handed”) if the direction of its spin is the same as the direction of its motion. It is negative (“left-handed”) if the directions of spin and motion are opposite.

Physics - Unpolarized Light Could Separate Chiral Molecules

WebThe most popular explanation for the existence of chiral edge states is probably the following: in a magnetic field, electrons move in cyclotron orbits, and such such cyclotron orbits ensure electrons to move in a single direction at the edge. That is why the edge state is chiral. I think this picture is too classical.
