All-electrical dephasing-protected spin qubits in altermagnets
José Carlos Abadillo-Uriel, Andrea Maiani, Alberto Cortijo +2
We propose altermagnetic semiconductors as a platform for field-free, all-electrically controlled spin qubits in gate-defined quantum dots. The momentum-dependent spin splitting of…
Directional conductance of Andreev crystals in hybrid Josephson junction arrays
Anders Enevold Dahl, Andrea Maiani, Max Geier +2
Andreev bound states are coherent electron-hole superpositions that form in a normal metal through repeated Andreev reflection at a superconducting interface. When the length of a…
Conductivity anisotropy and linear dichroism in spin-textured altermagnets
Andrea Maiani
Spin textures are ubiquitous in antiferromagnets, yet their consequences for altermagnets remain largely unexplored. We show that smooth spatial variations of the Néel order act o…
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…
Gatemonium: A Voltage-Tunable Fluxonium
William M. Strickland, Bassel Heiba Elfeky, Lukas Baker +6
We present a new style of fluxonium qubit, gatemonium, based on an all superconductorsemiconductor hybrid platform. The linear inductance is achieved using six hundred planar Al-In…
