28 Apr 2003 | | Journal: | Phys.Rev. B58 (1998) R8881 | | Subject: | Strongly Correlated Electrons | cond-mat.str-el hep-th | | Abstract: | For the model of frustrated spin-1/2 Heisenberg magnet described in A. A. Nersesyan and A. M. Tsvelik, (Phys. Rev. B{f 67}, 024422 (2003)) we calculate correlation functions of staggered magnetization and dimerization. The model is formulated as a collection of antiferromagnetic chains weakly coupled by a frustrated exchange interaction. The calculation done for the case of four chains demonstrates that these functions do not vanish. Since the correlation functions in question factorize into a product of correlation functions of spinon creation and annihilation operators, this constitutes a proof that spinons in this model propagate in the direction perpendicular to the chains. | | Source: | arXiv, cond-mat/0304634 | | Services: | Forum | Review | PDF | Favorites | |
