Triplet Cooper pair splitting in a two-dimensional electron gas

Kavli Affiliate: Srijit Goswami | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Cooper pairs occupy the ground state of typical s-wave superconductors and are composed of maximally entangled electrons with opposite spin. In order to study the spin and entanglement properties of these electrons, one must separate them spatially via a process […]
