Jason Alicea: Internally engineered Majorana modes in twisted bilayer graphene

CM Seminar

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.  I will also describe how electrical measurements of gate-defined wires can…
