摘要：
Temperature dependent high resolution photoemission spectra of quasi-one-dimensional Li0.9Mo6O17 evince a strong renormalization of its Luttinger-liquid density-of-states anomalous exponent. We trace this new effect to interacting charge neutral critical modes that emerge naturally from the two-band nature of the material. Li0.9Mo6O17 is shown thereby to be a paradigm material that is capable of revealing new Luttinger physics.
