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…
Vortex Tunneling and Critical State in an Oxide Heterostructure
Jordan T. McCourt, Ryan Henderson, John Chiles +5
Two-dimensional superconductors offer an excellent platform for the study of vortex matter due to their low superfluid stiffness and inability to effectively screen applied magneti…
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…
Creep-enhanced vortex pinning revealed through nonmonotonic relaxation of the Campbell length
Sunil Ghimire, Filippo Gaggioli, Kamal R. Joshi +9
We study the effects of flux creep on the linear AC response of the vortex lattice in single crystals CaIrSn by measuring the Campbell penetration depth, $λ_{\rm \sc…
Superconductivity in atomically thin films: 2D critical state model
Filippo Gaggioli, Gianni Blatter, Kostya S. Novoselov +1
The comprehensive understanding of superconductivity is a multi-scale task that involves several levels, starting from the electronic scale determining the microscopic mechanism, g…
