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…
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…
Pearl-Vortex Tunneling in Magic-Angle Twisted Graphene
Marta Perego, Peter Koopmann, Clara Galante Agero +8
Twisted graphene provides a tunable platform for studying superconductivity in two dimensions. In the presence of electric currents and magnetic fields, vortices determine the phen…
Experimental detection of vortices in magic-angle graphene
Marta Perego, Clara Galante Agero, Alexandra Mestre Torà +9
The tunability of superconducting magic-angle twisted-layer graphene films elevates this material system to a promising candidate for superconducting electronics. We implement a ga…
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…
