We present a theory of Coulomb blockade oscillations in tunneling through a
pair of quantum dots connected by a tunable tunneling junction. The positions
and amplitudes of peaks in the linear conductance are directly related,
respectively, to the ground state energy and to the dynamics of charge
fluctuations. We study analytically both strong and weak interdot tunneling. As
the tunneling decreases, the period of the peaks doubles, as observed
experimentally. In the strong tunneling limit, we predict a striking power law
temperature dependence of the peak amplitudes.Comment: 4 pages, revtex3.0, 1 figure uuencode
