| 英文摘要 | We perform a dimensional reduction of the U(1) x SU(2) Chem-Simons bosonization and we apply it to the t-J model relevant model for high T-c superconductors. This procedure yields a decomposition of the electron field into the product of two ''semionic'' fields, i.e. fields obeying abelian braid statistics with statistics parameter theta = 1/4, one carrying the charge and the other the spin degrees of freedom. A mean-field theory is then shown to reproduce correctly the large-distance behaviour of the correlation functions of the 1D t-J model at t much greater than J. This results shows that to capture the essential physical properties of the model one needs a specific ''semionic'' form of spin-charge separation. |
