Tunneling spectroscopy between two closely spaced parallel quantum wires shows non-interacting dispersion as well as excitation spectrum of interacting electrons in 1-dimensional wires [1-3]. In this work, we focus on the oscillation at low bias and low B-field regime of the tunneling spectroscopy and attribute it to the possible finite size effect resulting from the breaking of translational invariance.[1]
