We study the scaling properties of universal conductance fluctuations, observed in the magneto-resistance of quasi ballistic, split gate wires. In such devices the correlation field analysis is not simply determined by theoretical predictions for corresponding diffusive systems, and we discuss this
Recent results on the conductance fluctuations in disordered metals are reviewed and a heuristic argument for the universal conductance fluctuation is given.
The interplay between the use of random matrix theory and the semiclassical approach to describe conductance tluctuations in the ballistic regime is discussed. In order to understand the universal behavior as well as the correct physical scalings of conductance correlators one needs both theories. I
