The paper by C. W. J. Beenakker develops a linear-response theory for resonant tunneling through a quantum dot with small capacitance, focusing on the regime of thermally broadened resonances. This theory extends the classical theory of Coulomb-blockade oscillations by Kulik and Shekhter to the resonant-tunneling regime. The analysis considers both cases of negligible and strong inelastic scattering in the quantum dot. The effects of the non-Fermi-Dirac distribution of electrons among the energy levels are fully incorporated, especially when the thermal energy is comparable to the level separation. Explicit analytic results are derived for the periodicity, amplitude, line shape, and activation energy of the conductance oscillations. The theory is applied to explain the observed Coulomb-blockade oscillations in two-dimensional electron gases confined to narrow channels, providing insights into the underlying mechanisms and resolving the debate between Coulomb blockade and Wigner crystal explanations.The paper by C.
