Application of the semiclassical initial value representation and its linearized approximation to inelastic scattering

Ž . Ž . Ž . The semiclassical SC initial value representation IVR , and its linearized approximation LA , have been applied to the Ž . Ž . well-studied Secrest–Johnson model of colinear HeqH Õ TMHeqH Õ vibrationally inelastic scattering. The full 2 i 2 f SC–IVR treatment describes the quantum interference structure in the vibrational transition probabilities quantitatively, while the LA version...

Effect of inelastic scattering on the average Coulomb-blockade peak height in quantum dots

The average height of the Coulomb-blockade conductance peaks for chaotic elastic scattering is known to increase by a factor of 4/3 upon breaking time-reversal symmetry. We calculate the temperature dependence of this factor in the regime where the inelastic scattering rate G in is greater than the mean tunneling rate Gel , which itself is less than the mean level spacing D . Comparison to rece...

Elastic and inelastic scattering in quantum dots in the Coulomb-blockade regime.

Starting from a rate-equation model proposed by Beenakker, we calculate current-voltage characteristics for symmetric and asymmetric vertical quantum dots. We include up to 26 electrons and show how single-electron charge interaction, inelastic scattering, and nonadiabatic subband mixing can enhance the valley current signi6cantly by opening new conduction channels. Subband mixing is the domina...

Coulomb and nuclear excitation of giant dipole resonances in (a,a') inelastic scattering

Cross sections of inelastic a-particle scattering to isovector giant dipole resonances are calculated including both nuclear and Coulomb excitation. It is shown that the calculated cross sections are rather small and can be safely neglected for bombarding energies less than 200 MeV in determining the strength of the giant monopole resonance. This conclusion contradicts that of a recent report m...
