Internally engineered Majorana modes in twisted bilayer graphene
ORAL
Abstract
Twisted bilayer graphene (TBG) realizes an exquisitely tunable, strongly interacting system featuring superconductivity and various correlated insulating states. In this talk I will introduce gate-defined wires in TBG as an enticing platform for Majorana-based fault-tolerant qubits. Our proposal notably relies on "internally" generated superconductivity in TBG – as opposed to "external" superconducting proximity effects commonly employed in Majorana devices – and may operate even at zero magnetic field.
