Home > Press > Quantum quirk yields giant magnetic effect, where none should exist: Study opens window into the landscape of extreme topological matter
Rice University theoretical physicists (from left) Hsin-Hua Lai, Qimiao Si and Sarah Grefe worked with experimental collaborators at Vienna University of Technology to understand topological features of a nonmagnetic Weyl-Kondo semimetal allowed it to produce a giant Hall effect in the absence of a magnetic field.

Abstract:
In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect a characteristic change in the way electricity is conducted in the presence of a magnetic field in a nonmagnetic quantum material to which no magnetic field was applied.
