Abstract

A scaling theory is used to study the low-energy physics of electron-electron interactions in a double quantum dot. We show that the fact that electrons are delocalized over two quantum dots does not affect the instability criterion for the description of electron-electron interactions in terms of a “universal interaction Hamiltonian.”.
