Energy and particle number fluctuations in superconducting heterostructures
Ville J. Kauppila, Matti A. Laakso, Tero T. Heikkilä
We consider fluctuations of the energy on a mesoscopic island coupled to two leads. We use the Keldysh effective action formalism to derive the Langevin equation for the energy of…
