Topological quantum control: Edge currents via Floquet depinning of skyrmions in the $\nu = 0$ graphene quantum Hall antiferromagnet

15 Mar 2020 Iyer Deepak Foster Matthew S.

We propose a defect-to-edge topological quantum quench protocol that can efficiently inject electric charge from defect-core states into a chiral edge current of an induced Chern insulator. The initial state of the system is assumed to be a Mott insulator, with electrons bound to topological defects that are pinned by disorder... (read more)
