Researchers demonstrate the nematic quantum hill effect on crystal bismuth

Researchers from Princeton University and the University of Texas-Austin have demonstrated that electrons on a crystal bismuth exhibit the Nematic Quantum Hall Liquid effect at very low temperatures.

This is the first time that a quantum fluid of electrons is visualized. As valleytronics aims to exploit the energy level of electrons in relation to their momentum, this is an important step toward realizing this technology.
