Author(s): Y. Wang, K. Wohlfeld, B. Moritz, C. J. Jia, M. van Veenendaal, K. Wu, C.-C. Chen, and T. P. Devereaux Using cluster perturbation theory, we explain the origin of the strongly dispersive feature found at high binding energy in the spectral function of the Hubbard model. By comparing the Hubbard and t − J − 3 s model spectra, we show that this dispersion does not originate from either coupling to spin fluc… [Phys. Rev. B 92, 075119] Published Mon Aug 10, 2015
