In-plane and out-of-plane magnetic field driven Josephson diode effect in magic-angle twisted four-layer graphene
Marta Perego, Sayan Banerjee, Mohamad Abu El Hija +8
The superconducting diode effect offers a powerful probe into the fundamental symmetries of quantum materials. Recent studies on twisted graphene diodes have predominantly focused…

Fully gapped superconductivity in magic-angle graphene Cooper-pair islands
Alexandra Mestre-Torà, Marta Perego, Clara Galante Agero +5
The mechanism behind superconductivity in magic-angle graphene systems remains an open question. Recent tunnelling and superfluid stiffness measurements have suggested a nodal supe…
