摘要：
We present calculation of optical conductivity in a simple model of electronic spectrum of two-dimensional system with "hot patches" on the Fermi surface, leading to non Fermi-liquid renormalization of the spectral density (pseudogap) on these patches. Based upon "nearly"-exact solution for the two-particle Green's function it is shown that this model qualitatively reproduces basic anomalies of optical experiments in the pseudogap state of copper oxides.
