It is shown that Coulomb interaction substantially enhances the probability of big current fluctuations for short conductors with $E_{\\rm Th}\\gg1/\\tau_E$, $\\tau_E$ being the energy relaxation time, leading to the exponential tails in the current distribution. The current fluctuations are most strong for low temperatures, provided $E_{\\rm Th}\\sim [(eV)^2/D\\nu_1^2\\bigr]^{1/3}$ for 1D and $E_{\\rm Th}\\sim (eV/g)\\ln g$ for 2D, where $g$ is a dimensionless conductance and $\\nu_1$ is a 1D density of states. The FCS in the \"hot electron\" regime is also discussed.", "revisions": [ { "version": "v1", "updated": "2004-06-21T17:16:08.000Z" } ], "analyses": { "keywords": [ "full current statistics", "cold electrons", "coulomb interaction substantially enhances", "big current fluctuations", "energy relaxation time" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
