Cooper pair splitter in a photonic cavity: Detection of Andreev scatterings
arXiv:2209.00866 · doi:10.1103/PhysRevB.106.085424
Abstract
We simulated the radiative response of the cavity quantum electrodynamics (QED) coupled to the double quantum dot Cooper pair splitter and analyzed its spectral dependence to get insight into dynamics of the Cooper pair transfers. The model is confined to the energy subspace where two entangled electrons are transferred to two normal electrodes through the inter-dot singlet state on two proximitized quantum dots. Our research is focused on the Andreev scatterings in the subgap regime, for which the local charge susceptibility is derived, by means of Keldysh Green functions, in a whole bias voltage range. In particular, in the large voltage limit the spectrum of is expressed by a simple analytical formula, which shows various dissipation processes related with photon-induced transitions between the Andreev bound states.
