New quantum oscillations observed in graphene moiré systems reveal nonlinear Hall effect properties

phys.org

Physicists discovered a new quantum oscillation in graphene moiré systems related to the nonlinear Hall effect. This phenomenon involves a voltage perpendicular to current, influenced by electron wave function geometry. The research reveals how magnetic fields affect this effect in twisted graphene layers. The findings offer a new method to study exotic quantum states like Wigner crystals and understand complex quantum material behaviors.
