Charge Fluctuations in the Edge States of N-S hybrid Nano-Structures
Andrew M. Martin, Thomas Gramespacher, Markus Buttiker
In this work we show how to calculate the equilibrium and non-equilibrium charge fluctuations in a gated normal mesoscopic conductor which is attached to one normal lead and one su…
Distribution functions and current-correlations in normal-metal--superconductor hetero-structures
Thomas Gramespacher, Markus Buttiker
We introduce electron-like and hole-like distribution functions, which determine the currents and the fluctuation spectra of the currents measured at a normal-conductor--supercondu…
Charge fluctuations in a quantum point contact attached to a superconducting lead
Andrew M. Martin, Thomas Gramespacher, Markus Buttiker
We show how to calculate the charge noise spectrum in a normal mesoscopic conductor, which is capacitively coupled to a macroscopic gate, when this conductor is attached to L norma…
Local densities, distribution functions, and wave function correlations for spatially resolved shot noise at nanocontacts
Thomas Gramespacher, Markus Buttiker
We consider a current-carrying, phase-coherent multi-probe conductor to which a small tunneling contact is attached. We treat the conductor and the tunneling contact as a phase-coh…
Local non-equilibrium distribution of charge carriers in a phase-coherent conductor
Thomas Gramespacher, Markus Buttiker
We use the scattering matrix approach to derive generalized Bardeen-like formulae for the conductances between the contacts of a phase-coherent multiprobe conductor and a tunneling…
Quantum shot-noise at local tunneling contacts on mesoscopic multiprobe conductors
Thomas Gramespacher, Markus Buttiker
New experiments that measure the low-frequency shot-noise spectrum at local tunneling contacts on mesoscopic structures are proposed. The current fluctuation spectrum at a single t…
