Interaction Constants and Dynamic Conductance of a Gated Wire
Interaction Constants and Dynamic Conductance of a Gated Wire
We show that the interaction constant governing the long-range electron-electron interaction in a quantum wire coupled to two reservoirs and capacitively coupled to a gate can be determined by a low-frequency measurement. We present a self-consistent, charge and current conserving, theory of the full conductance matrix. The collective excitation spectrum …
