Proximity-induced superconductivity in a bilayer graphene quantum point contact
Clara Galante-Agero, Christoph Adam, Artem O. Denisov +9
We report the realization of a gate-defined quantum point contact (QPC) in bilayer graphene proximitized by a single aluminum superconducting electrode. Superconducting correlation…
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-TorÃ, 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…
Quasiparticle and superfluid dynamics in Magic-Angle Graphene
ElÃas Portolés, Marta Perego, Pavel A. Volkov +12
Magic-Angle Twisted Bilayer Graphene shows a wide range of correlated phases which are electrostatically tunable. Despite a growing knowledge of the material, there is yet no conse…
