Abstract

We report quantum interferences in a multi-channel Luttinger liquid coupled by a microwave field at two pinning sites where electrons experience forward scattering. We use a magnetic field to tune the phase difference between charge density waves propagating in each channel. The interferences give a field dependent transmission through the second pining site which we detect through oscillations in the magneto-resistance. Experimental data fit quantitatively the response of the Luttinger liquid confined by a spatially varying magnetic field and yield the distance between pining centres (11 mu m) as the only adjustment parameter.
