Abstract
We investigate a superconducting quantum interference device based on carbon nanotubes in a fork geometry [J.-P. Cleuziou et al., Nat. Nanotechnol. 1, 53 (2006)], involving tunneling of evanescent quasiparticles through a superconductor over a distance comparable to the superconducting coherence length, with therefore “nonlocal” processes generalizing nonlocal Andreev reflection and elastic cotunneling. Nonlocal processes induce a reduction of the critical current and modify the current-phase relation. We discuss arbitrary interface transparencies. Such devices in fork geometries are candidates for probing the phase coherence of crossed Andreev reflection.
