    • The average numbers of phonons per site would be □ b iα † bi α □ ≈0.5 and □ b iβ † biβ □ ≈0.1 even if they are slightly dependent on Aex. The lattice energy Elattice absorbed from the photoexcitation would then be Elattice ≈0.08.

    • To obtain the known ground state [i.e., (0110) state], in addition to H0, we have actually considered the infinitesimal on-site energy term that breaks the translational symmetry of H0, i.e., iσ εi c iσ † ciσ, where εi =+δ, -δ, -δ, +δ,... (i=0,1,2,3,...) and δ/t= 10-5.

    • Conceptually, in the present problem, we remove holes through the photoemission process. However, we prefer the term photoelectron for convenience and also display spectra according to negative binding energy as for the usual PES. Therefore, the spectra in Fig. 5 can be simply understood as being from the quarter-filled electron system.
