16 Jan 2007 | | Subject: | Strongly Correlated Electrons; Statistical Mechanics | | Abstract: | We study theoretically the destruction of spin nematic order due to quantum fluctuations in quasi-one dimensional spin-1 magnets. If the nematic ordering is disordered by condensing disclinations then quantum Berry phase effects induce dimerization in the resulting paramagnet. We develop a theory for a Landau-forbidden second order transition between the spin nematic and dimerized states found in recent numerical calculations. Numerical tests of the theory are suggested. | | Source: | arXiv, cond-mat/0701361 | | Services: | Forum | Review | PDF | Favorites | |
