Query: Finite Size Scaling Behavior of Dissipative Tunnel Junctions   We present the results of a series of Quantum Monte Carlo calculations of the
temperature dependent conductance of dissipative non-superconducting tunnel
junctions. Finite size scaling methods are used to demonstrate the absence of
coherent transport in Ohmic tunnel junctions. However, a quantum phase
transition between coherent and incoherent behavior is found in sub-Ohmic
tunnel junctions. The critical conductance is found to be temperature
independent and the critical exponents, $\nu$ and $\eta$, are found to be in
agreement with renormalization group results by Kosterlitz.
