Vortex Dynamics in Magic-Angle Twisted Graphene
Marta Perego, Peter Koopmann, Clara Galante Agero +7
We use a gate-defined Josephson junction (JJ) device made from twisted-layer graphene for studying vortex dynamics in two dimensions. The JJ sensor signals the presence of individu…

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…

Monolithic hybrid quantum dot devices in superconducting twisted bilayer graphene
Alexandra Mestre-Torà, Marta Perego, Clara Galante Agero +5
Gate-tunable superconductivity in magic-angle twisted bilayer graphene (MATBG) has enabled the realization of superconducting devices, such as Josephson junctions, within a single…
