We show that effectively cold metastable states in one-dimensional photodoped Mott insulators described by the extended Hubbard model exhibit spin, charge, and q-spin separation. Their wave functions in the large on-site Coulomb interaction limit can be expressed as IW) = IWcharge)IWspin)IWq-spin), which is analogous to the Ogata-Shiba states of the doped Hubbard model in equilibrium. Here, the q-spin represents the type of photo-generated pseudoparticles (doublon or holon). IWcharge) is determined by spinless free fermions, IWspin) by the isotropic Heisenberg model in the squeezed spin space, and IWq-spin) by the XXZ model in the squeezed q-spin space. In particular, the metastable q-pairing and charge-density-wave (CDW) states correspond to the gapless and gapful states of the XXZ model. The specific form of the wave function allows us to accurately determine the exponents of correlation functions. The form also suggests that the central charge of the q-pairing state is 3 and that of the CDW phase is 2, which we numerically confirm. Our study provides analytic and intuitive insights into the correlations between active degrees of freedom in photodoped strongly correlated systems.
