Double quantum dot as a probe of nonequilibrium charge fluctuations at the quantum point contact
Double quantum dot as a probe of nonequilibrium charge fluctuations at the quantum point contact
Absorption of energy quanta generated by a quantum point contact results in the inelastic current through a double quantum dot placed nearby. In contrast to a single quantum dot, the inelastic current through the double quantum dot is determined by the nonlocal current correlations in the quantum point contact, which …
