WebDec 17, 2012 · The ordering vectors are displayed in G – I. ( J – L) All spectra are calculated at T < TCDW2 and include both CDWs (Eq. S2 ). ( J and K) For parallel polarizations, one observes only the CDW with ordering vector perpendicular to the light polarizations. The response of the respective orthogonal CDW is too weak to be visible.
