Observing Laughlin's pump using quantized edge states in graphene
Bjarke S. Jessen, Maëlle Kapfer, Yuhao Zhao +4
Laughlin's thought experiment of quantized charge pumping is central to understanding the integer quantum Hall effect (IQHE) and the topological origin of its conductance quantizat…

Twist-Angle-Controlled Anomalous Gating in Bilayer Graphene/BN Heterostructures
G. Maffione, L. S. Farrar, M. Kapfer +5
Anomalous gating effects-such as gate ineffectiveness and pronounced hysteresis-have been observed in graphene-based systems encapsulated in boron nitride (BN) and linked to a poss…
