Abstract
We develop a non-perturbative theory for describing decoherence dynamics of electron charges in the double quantum dot gated by electrodes. We extend the Feynman-Vernon's influence functional theory to fermionic environments and derive an exact master equation for the reduced density matrix of electrons in the double dot for a general spectral density at arbitrary temperature and bias.
