Shot noise in the quantum-to-classical crossover regime

Abstract: Recent results on shot noise and full electron counting statistics in phase-coherent transport through quantum dots will be presented. By numerically simulating transport through ballistic and disordered two-dimensional cavities, we find that the amount of shot noise suppression for regular systems is surprisingly similar to the noise suppression in chaotic or disordered cavities. I will discuss how this finding can be understood in terms of diffractive scattering at the cavity openings, which act as very strong noise sources. Furthermore the emergence of 'noiseless scattering states' in the quantum-to-classical crossover of transport will be addressed.
