One-dimensional electronic fluids are peculiar conducting systems, where thefundamental role of interactions leads to exotic, emergent phenomena, such asspin-charge (spinon-holon) separation. The distinct low-energy properties ofthese 1D metals are successfully described within the theory of linearLuttinger liquids, but the challenging task of describing their high-energynonlinear properties has long remained elusive. Recently, novel theoreticalapproaches accounting for nonlinearity have been developed, yet the richphenomenology that they predict remains barely explored experimentally. Here,we probe the nonlinear spectral characteristics of short GaAs quantum wires bytunnelling spectroscopy, using an advanced device consisting of 6000 wires. Wefind evidence for the existence of an inverted (spinon) shadow band in the mainregion of the particle sector, one of the central predictions of the newnonlinear theories. A (holon) band with reduced effective mass is clearlyvisible in the particle sector at high energies.
