Impurity states in altermagnetic superconductors
Andrea Maiani, Rubén Seoane Souto
Altermagnetic superconductors offer the possibility of exploring unconventional superconductivity, including topological states and finite-momentum superconductivity, with promisin…
Percolative supercurrent in superconductor-ferromagnetic insulator bilayers
A. Maiani, A. C. C. Drachmann, L. Galletti +4
We report tunneling spectroscopy and transport measurements in superconducting Al and ferromagnetic-insulator EuS bilayers. The samples display remanent spin-splitting, roughly hal…
Supercurrent reversal in ferromagnetic hybrid nanowire Josephson junctions
D. Razmadze, R. Seoane Souto, L. Galletti +7
We report supercurrent transport measurements in hybrid Josephson junctions comprised of semiconducting InAs nanowires with epitaxial ferromagnetic insulator EuS and superconductin…
Vortex nucleation barriers and stable fractional vortices near boundaries in multicomponent superconductors
Andrea Maiani, Andrea Benfenati, Egor Babaev
The magnetization process of a superconductor is determined by the potential barrier for vortex nucleation and escape. In multicomponent superconductors, fractional vortices with a…
Vortex nucleation barrier in superconductors beyond the Bean-Livingston approximation: A numerical approach for the sphaleron problem in a gauge theory
Andrea Benfenati, Andrea Maiani, Filipp N. Rybakov +1
The knowledge of vortex nucleation barriers is crucial for applications of superconductors, such as single-photon detectors and superconductor-based qubits. Contrarily to the probl…
