Fermi liquid theory of La2-xSrxCuO4

  • 1. Massachusetts Inst. of Tech., Cambridge, MA (USA). Dept. of Physics

Description

The authors treat a model with orbitals on the copper and oxygen sites and hopping between them. In the limit of infinite U on the Cu site, the problem is treated using the slave boson method. In the presence of doping, they find a Fermi liquid solution with mass enhancement proportional to x-1. A new feature in the optical absorption is found with oscillator strength proportional to x, which can explain a peak at 0.5 eV observed experimentally. The interaction between quasi-particles via the exchange of slave bosons is discussed
