Coherent voltage oscillations in small normal tunnel junctions and the crossover to the incoherent regime

by Y. Gefen
We discuss the possibility of charge oscillations in a normal tunnel junction, driven by an external current source (Iex), in the coherent limit. In that limit the dephasing time tɸ is larger than the period tp ≡ e/Iex. This behavior is modified when tɸ decreases.
