Abstract
We calculate the finite-temperature conductance peak-height distributions in Coulomb-blockade quantum dots in the limit where the inelastic-scattering rate in the dot is large compared with the mean elastic tunneling rate. The relative reduction of the standard deviation of the peak-height distribution by a time-reversal symmetry-breaking magnetic field is enhanced by the inclusion of inelastic scattering at finite temperature (in contrast to the elastic limit where this reduction is essentially temperature independent). We suggest this quantity as an independent experimental probe for inelastic scattering in closed dots.
