Frequency-dependent third cumulant of current in diffusive conductors
Frequency-dependent third cumulant of current in diffusive conductors
We calculate the frequency dispersion of the third cumulant of current in diffusive-metal contacts. The cumulant exhibits a dispersion at the inverse time of diffusion across the contact, which is typically much smaller than the inverse $RC$ time. This dispersion is much more pronounced in the case of strong electron-electron …
