Temperature dependent optical conductivity of undoped cuprates with weak exchange
J. Malek, S. -L. Drechsler, U. Nitzsche +2
The optical conductivity sigma(omega) is calculated at finite temperature T for CuO_2 chain clusters within a pd-Hubbard model. Data at T = 300 K for Li_2CuO_2 are reanalyzed withi…
