Query: Gapped electron fractionalization in robustly one dimensional
  Li0.9Mo6O17   The angle resolved photoemission spectroscopy lineshapes of quasi
one-dimensional (1d) Li0.9Mo6O17 display both agreement with and departures
from the one-band Tomonaga-Luttinger model. We show that the departures can be
understood by explicitly accounting for the four modes arising from the two
quasi-1d bands known to cross the Fermi energy. The key assumption is that the
antisymmetric charge mode is gapped with a magnitude near the temperature (T)
of a mysterious 25K powerlaw resistivity upturn. The gap is consistent with the
lack of a charge or spin density wave accompanying the upturn, is able to
control the upturn T, and prevents crossover to a Fermi liquid (FL) down to the
superconducting transition at 1.9K.
