Chirality means properties of a system that are changed in its mirror image. In recent years chirality has become such a prevailing word in condensed matter physics that sometimes its meaning in certain contexts is not immediately clear. I will start this talk by explaining why chirality is intuitively associated with magnetism and the transport phenomena called Hall effects. This connection leads to a class of “chiral antiferromagnets” that people start to be interested in recently, which are antiferromagnets having the anomalous Hall effect. I will then propose a new “chiral” quantity, coined electronic chiralization (EC). [Read more…]
