The study of one-dimensional electron systems is facilitated by creating very clean, single mode electronic wave guides. In our research we study the low temperature transport properties of these one-dimensional conductors while varying their density and disorder. We show that the strong interactions among the electrons modify completely their ground state properties. We also study tunneling between two parallel wires which enables direct determination of the many-body excitation spectrum of the system.
