dc.descriptionThe effect of an invasive voltage probe on the phase-coherent conduction through a ballistic chaotic cavity is investigated by random-matrix theory. The entire distribution P(G) of the conductance G is computed for the case that the cavity is coupled to source and drain by two point contacts with a quantized conductance of 2 e^2/h, both in the presence (beta = 1) and absence (beta = 2) of time-reversal symmetry. The loss of phase-coherence induced by the voltage probe causes a crossover from P(G) ~ G^(-1 + beta/2) to a Gaussian centered at G = e^2/h with a beta-dependent width. ***Submitted to Physical Review B.***
