Abstrakti

Investigations of electrical noise and fluctuations in mesoscopic conductors have traditionally involved measurements of the shot noise and the full counting statistics of transferred charges [1], [2], [3]. Recently, the distribution of waiting times between consecutive electrons has been suggested as another useful and complementary characterization of stochastic quantum transport. In this contribution, we provide a brief overview of our recent Geneva efforts to describe and evaluate the electronic waiting time distributions for several types of quantum conductors. For driven single-electron emitters described by quasi-classical master equations, the electronic waiting time distribution provides us with a simple and intuitive picture of the charge transport [4]. For fully phase-coherent conductors, we have formulated a compact determinant formula based on scattering theory that for instance predicts a crossover in the waiting time distribution for a quantum point contact from Wigner-Dyson statistics at full transmission to Poisson statistics close to pinch-off [5]. Finally, to describe the influence of dephasing as well as non-Markovian dynamics, we have employed an open-quantum-systems approach and evaluated the waiting times between electrons propagating through a dissipative double quantum dot [6]. We conclude by providing an outlook on future work and identify possible avenues for further developments.
