Abstract
We calculate using linear-response theory the admittance of a quantum dot out of equilibrium. The interaction between two electrons with opposite spins simultaneously residing on the resonant level is modeled by an Anderson Hamiltonian. The electron correlations lead to the appearance of another feature in the frequency dependence of the conductance. For certain parameter values there are two crossover frequencies between capacitive and inductive behavior of the imaginary part of the admittance. The experimental implications of the obtained results are briefly discussed.Keywords
