New Luttinger liquid physics from photoemission on Li${}_{0.9}$Mo${}_6$O${}_{17}$

Feng Wang, J. V. Alvarez, S. -K. Mo +6

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-state…
