Resumen:
We introduce a path-integral approach that allows us to compute charge-density oscillations in a Luttingerliquid with impurities. We obtain an explicit expression for the envelope of Friedel oscillations in the presenceof arbitrary electron-electron potentials. As examples, in order to illustrate the procedure, we show how to useour formula for contact and Coulomb potentials.
