A Mesoscopic Resonating Valence Bond system on a triple dot
Karyn Le Hur, Patrik Recher, Emilie Dupont +1
We introduce a mesoscopic pendulum from a triple dot. The pendulum is fastened through a singly-occupied dot (spin qubit). Two other strongly capacitively islands form a double-dot…
Decoherence of Einstein-Podolsky-Rosen pairs in a noisy Andreev entangler
Emilie Dupont, Karyn Le Hur
We investigate quantum noise effect on the transportation of nonlocal Cooper pairs accross the realistic Andreev entangler which consists of an s-wave superconductor coupled to two…
Do quantum dots allow one access to pseudogap Kondo physics?
John Hopkinson, Karyn Le Hur, Emilie Dupont
For the last decade, tunable quantum dot systems have allowed the investigation of Kondo physics wherein the quenching of a single spin on an artificial atom affects the conductanc…
Quantum dot in the pseudogap Kondo state
J. Hopkinson, K. Le Hur, E. Dupont
We investigate the transport properties of a (small) quantum dot connected to Fermi liquid leads with a power-law density of states (DOS). Such a system, if experimentally realizab…
