摘要：

We derive closed expressions for the universal weak-localization peak of the average conductance peak heights in Coulomb blockade quantum dots in the crossover from orthogonal to unitary symmetry. The scale for the crossover is independent of the number of channels in each lead, in contrast with the case of open dots. The functional form of the weak-localization peak is independent of temperature. We also derive analytically the variance of the conductance peak heights as a function of the crossover parameter.
