THE EFFECTS OF INELASTIC-SCATTERING IN OPEN QUANTUM DOTS - REDUCTION OF CONDUCTANCE FLUCTUATIONS AND DISRUPTION OF WAVE-FUNCTION SCARRING

We perform numerical simulations of the quantum mechanical transport a nd corresponding wave-functions in open, square quantum dots. The effe cts of inelastic scattering are introduced phenomenologically. Examini ng the root mean square amplitude of the conductance fluctuations, we find they decay exponentially with 1/tau(phi) (tau(phi) being the inel astic scattering time), in good agreement with the results of recent e xperiments. In previous work, we have found the wave-functions of such dots should be 'scarred'. We examine the robustness of this scarring effect to the phase-breaking process.
