Fig. 5: Equilibrium two-electron states at finite hopping t0.

a The phonon number Np increases as the electron-phonon coupling becomes stronger and is more smooth for a larger t0. b, c The order parameter O and CDW structure factor C get reduced, but the three equilibrium regimes discovered in the atomic limit still survive under small but finite t0. Here we set U1/2πℏ = 200 GHz, U2/2πℏ = 20 GHz, U3/2πℏ = 2 GHz, and ω0/2π = 3 GHz. The local chemical potential ε is ignored for the two-electron case, and the bias voltage is set to zero for these plots.
