Spin superfluidity and graphene in a strong magnetic field

Speaker: Bert Halperin, Harvard University

When: March 28, 2017 (Tue), 03:30PM to 04:30PM (add to my calendar)
Location: COM 101
Hosted by: David Campbell

This event is part of the Physics Department Colloquia Series. Refreshments will be served at 3:15.

The ground state of neutral monolayer graphene in a strong perpendicular magnetic field is believed to be the so-called “canted antiferromagnetic ν = 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. The talk will explain the underlying concepts and will discuss a proposed experiment to demonstrate this effect.
