Gapped electron fractionalization in robustly one dimensional Li0.9Mo6O17

13 Oct 2016 Lera Natalia Alvarez J. V. Allen J. W.

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... (read more)
