Fractal conductance fluctuations in generic chaotic cavities
Fractal conductance fluctuations in generic chaotic cavities
It is shown that conductance fluctuations due to phase coherent ballistic transport through a chaotic cavity generically are fractals. The graph of conductance vs. externally changed parameter, e.g. magnetic field, is a fractal with dimension D=2-b/2 between 1 and 2. It is governed by the exponent b (<2) of the …
