13 Mar 2002 | Journal: | PRB 66, 073105 (2002) | Subject: | Strongly Correlated Electrons | cond-mat.str-el | Affiliation: | NORDITA | Abstract: | We study the optical response of a strongly correlated electron system near the metal-insulator transition using a mapping to the sine-Gordon model. With semiclassical quantization, the spectral weight is distributed between a Drude peak and absorption lines due to breathers. We calculate the Drude weight, the optical gap, and the lineshape of breather absorption. | Source: | arXiv, cond-mat/0203273 | Services: | Forum | Review | PDF | Favorites |
