Physics Seminar: Spin Superfluidity in the nu=0 Quantum Hall State of Graphene
Dr. So Takei
Queens College of CUNY
The ground state of neutral monolayer graphene in a strong perpendicular magnetic field is believed to be the so-called canted antiferromagnetic nu=0 quantum Hall state. This state is an insulator for charge transport, but it should behave like a superfluid for transport of the spin component parallel to the magnetic field. Here, we have proposed an experiment to demonstrate this effect.
