Query: Real-time renormalization group and charge fluctuations in quantum dots   We develop a perturbative renormalization-group method in real time to
describe nonequilibrium properties of discrete quantum systems coupled linearly
to an environment. We include energy broadening and dissipation and develop a
cutoff-independent formalism. We present quantitatively reliable results for
the nonlinear conductance in the mixed-valence and empty-orbital regime of the
nonequilibrium Anderson impurity model with finite on-site Coulomb repulsion.
