Mazin I.I., Maksimov E. G., Rashkeev S. N., Savrasov S. Yu., Uspenskii Yu. A.
The electronic structure and optical spectra of the compound La2Cu04 in the tetragonal phase are calculated "from first principles." The results show that all the basic features of the observed reflection spectrum can be explained by the conventional band approach.
