Semiclassical theory of Coulomb blockade peak heights in chaotic quantum dots
We develop a semiclassical theory of Coulomb blockade peak heights in chaotic quantum dots. Using Berry’s conjecture, we calculate peak height distributions and correlation functions. We demonstrate that corrections to the corresponding results of the standard statistical theory are nonuniversal, and can be expressed in terms of the classical periodic orbits of the dot that are well coupled to ...
متن کاملEffects of spin and exchange interaction on the Coulomb-blockade peak statistics in quantum dots.
We derive a closed expression for the linear conductance through a quantum dot in the Coulomb-blockade regime in the presence of a constant exchange interaction. With this expression we calculate the temperature dependence of the conductance peak-height and peak-spacing statistics in chaotic quantum dots. Using a realistic value of the exchange interaction, we find significantly better agreemen...
متن کاملCoulomb blockade in Quantum Dots
In the resonant tunnelling diode we have treated electrons as non interacting particles. We have discussed their wave nature, which led to quantized energy states in small and coherent cavities. Qualitatively this is due to the requirement that an integer number of Fermi wavelengths has to fit between the barriers. Here we begin in the opposite limit by neglecting space quantization effects in ...
متن کاملCoulomb Blockade Fluctuations in Disordered Quantum Dots
We discuss some recent results on the statistics of the Coulomb Blockade in disordered quantum dots containing spinless interacting fermions using the self-consistent Hartree-Fock approximation. We concentrate on the regime rs > ∼ 1, with finite dimensionless conductance g. We present significantly different results for the cases of a Coulomb and a nearest-neighbour bare interaction. We show th...
متن کاملSpectral scrambling in Coulomb - blockade quantum dots
We estimate the fluctuation width of an energy level as a function of the number of electrons added to a Coulomb-blockade quantum dot. A microscopic calculation in the limit of Koopmans’ theorem predicts that the standard deviation of these fluctuations is linear in the number of added electrons, in agreement with a parametric random-matrix approach. We estimate the number of electrons it takes...
