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…
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…
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…
Campbell penetration in the critical state of type-II superconductors
R. Willa, V. B. Geshkenbein, G. Blatter
The penetration of an magnetic signal into a type II superconductor residing in the Shubnikov phase depends on the pinning properties of Abrikosov vortices. Within a phenomeno…
Suppression of Geometric Barrier in Type II Superconducting Strips
R. Willa, V. B. Geshkenbein, G. Blatter
We study the magnetic response of a superconducting double strip, i.e., two parallel coplanar thin strips of width , thickness and of infinite length, separated by a…
Surface Melting of the Vortex Lattice in Layered Superconductors: Density Functional Theory
A. De Col, G. I. Menon, V. B. Geshkenbein +1
We study the effects of an -surface on the vortex-solid to vortex-liquid transition in layered superconductors in the limit of vanishing inter-layer Josephson coupling. We deri…
