New Luttinger liquid physics from photoemission on Li $_{0.9}$ Mo $_{6}$ O $_{17}$

arXiv:cond-mat/0604503 · doi:10.1103/PhysRevLett.96.196403

Abstract

Temperature dependent high resolution photoemission spectra of quasi-1 dimensional Li $_{0.9}$ Mo $_{6}$ O $_{17}$ 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. Li $_{0.9}$ Mo $_{6}$ O $_{17}$ is shown thereby to be a paradigm material that is capable of revealing new Luttinger physics.
