Low-temperature Dephasing and Renormalization in Model Systems
Dmitri S. Golubev, Gerd Schön, Andrei D. Zaikin
We investigate low-temperature dephasing in several model systems, where a quantum degree of freedom is coupled to a bath. Dephasing, defined as the decay of the coherence of inita…

Low temperature decoherence by electron-electron interactions: Role of quantum fluctuations
Dmitri S. Golubev, Andrei D. Zaikin
We derive a general expression for the conductivity of a disordered conductor with electron-electron interactions (treated within the standard model) and evaluate the weak localiza…
