Signatures of Andreev Blockade in a Double Quantum Dot Coupled to a Superconductor
Signatures of Andreev Blockade in a Double Quantum Dot Coupled to a Superconductor
We investigate an electron transport blockade regime in which a spin triplet localized in the path of current is forbidden from entering a spin-singlet superconductor. To stabilize the triplet, a double quantum dot is created electrostatically near a superconducting Al lead in an InAs nanowire. The quantum dot closest to …
