8 May 2002 | Journal: | International Journal of Modern Physics B, Vol. 16, No. 25 (2002) 3759-3770 | Subject: | Strongly Correlated Electrons | cond-mat.str-el | Abstract: | A phenomenological approach is presented that allows one to model, and thereby interpret, photoemission spectra of strongly correlated electron systems. A simple analytical formula for the self-energy is proposed. This self-energy describes both coherent and incoherent parts of the spectrum (quasiparticle and Hubbard peaks, respectively). Free parameters in the expression are determined by fitting the density of states to experimental photoemission data. An explicit fitting is presented for the La$_{1-x}$Sr$_x$TiO$_3$ system with $0.08 le x le 0.38$. In general, our phenomenological approach provides information on the effective mass, the Hubbard interaction, and the spectral weight distribution in different parts of the spectrum. Limitations of this approach are also discussed. | Source: | arXiv, cond-mat/0205149 | Services: | Forum | Review | PDF | Favorites |
