Spontaneous vortex-antivortex lattice and Majorana fermions in rhombohedral graphene
Filippo Gaggioli, Daniele Guerci, Liang Fu
The discovery of superconducting states in multilayer rhombohedral graphene with spin and valley polarization has raised an interesting question: how does superconductivity cope wi…
Nonreciprocity of supercurrent along applied magnetic field
Filippo Gaggioli, Yasen Hou, Jagadeesh S. Moodera +1
Nonreciprocal current responses arise in a broad range of systems, from magnons and phonons to supercurrents, due to an interplay between spatial and temporal symmetry breakings. T…
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 \s…
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…
