Investigations of Crossed Andreev Reflection in Hybrid Superconductor-Ferromagnet Structures
Cooper pair splitting is predicted to occur in hybrid devices where a superconductor is coupled to two ferromagnetic wires placed at a distance less than the superconducting coherence length. This thesis searches for signatures of this process, called crossed Andreev reflection (CAR), in three …

Investigations of nonlocal transport and current noise in mesoscopic normal metal-superconductor hybrid structures
… of entangled spin-singlet electrons provided Cooper pairs can be split without losing wavefunction coherence. In Cooper pair-splitter devices the electrodes (or quantum dots) are coupled to a superconductor with a separation of less than or equal to the superconducting coherence length. At …

Counting nonequilibrium quasiparticles in a superconductor
Superconductivity is based on the Cooper pairing of electrons, which enables flow of electrical current without resistance, expulsion of magnetic fields in the Meissner effect, as well as electrical circuits obeying the rules of quantum mechanics. Such superconducting circuits are currently under …

Charge dynamics in superconducting double dots
… of a two level manifold of even charge parity Cooper pair states, and continuous bands corresponding to charge states with single quasiparticles in one or both islands. These devices are fabricated using shadow mask evaporation, and are measured at sub Kelvin temperatures using a dilution …
