Coulomb drag in quantum circuits

Alex Levchenko, Alex Kamenev

We study drag effect in a system of two electrically isolated quantum point contacts (QPC), coupled by Coulomb interactions. Drag current exhibits maxima as a function of QPC gate…

Josephson current noise above Tc in superconducting tunnel junctions

Alex Levchenko

Tunnel junction between two superconductors is considered in the vicinity of the critical temperature. Superconductive fluctuations above Tc give rise to the noise of the ac Joseph…
