On the scaling approach to electron-electron interactions in a chaotic quantum dot
arXiv:cond-mat/0309074 · doi:10.1103/PhysRevB.68.241311
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''.
