12 Dec 2016 | | Abstract: | A strong coupling between an electronic cavity and a quantum dot has been
recently demonstrated [Phys. Rev. Lett. 115, 166603 (2015)]. Here, we highlight
the experimental signatures that demonstrate the cavity’s impact on inelastic
singlet-triplet transport through the dot. In parallel, we propose and analyze
a model that describes the coupled dot--cavity system and predicts the same
transport signatures. In our solution, we use a combination of an exact
treatment of the dot--cavity hybridization to all orders, with lowest-order
treatment of the coupling to electronic leads using a master equation approach.
Interestingly, this is sufficient for highlighting the interplay between the
cavity and the higher-order inelastic singlet-triplet cotunneling. | | Source: | arXiv, 1612.3850 | | Services: | Forum | Review | PDF | Favorites | |
