Static and dynamic image potential for tunneling into a Luttinger liquid
arXiv:cond-mat/0004305 · doi:10.1016/S0038-1098(00)00425-7
Abstract
We study electron tunneling from a tip or a lead into an interacting quantum wire described by Luttinger liquid theory. Within a WKB-type approach, the Coulomb interaction between the wire and the tunneling electrons, as well as the finite traversal time are taken into account. Although the static image potential is only logarithmically suppressed against the bare Coulomb interaction, the dynamic image potential is not strong enough to alter power-law exponents entering the tunneling density of states.
