✦ Synopsis
Superconducting tunnel junctions with dissipation show a zero temperature phase transition at a critical strength of the dissipation. The dissipation can be due to different mechanismes: an Ohmic current, single electron tunneling, or a current flow through a normal constriction. It is known that the phase transitions differ in several respects for the first two cases. It is the purpose of this article to discuss the nature of the dissipative phase transition if it arises due to the third mechanisme.
