Spectral functions of the onedimensional Hubbard model in the U{r_arrow}+{infinity} limit: How to use the factorized wave function
Abstract
We give the details of the calculation of the spectral functions of the onedimensional Hubbard model using the spincharge factorized wave function for several versions of the U{r_arrow}+{infinity} limit. The spectral functions are expressed as a convolution of charge and spin dynamical correlation functions. A procedure to evaluate these correlation functions very accurately for large systems is developed, and analytical results are presented for the lowenergy region. These results are fully consistent with the conformal field theory. We also propose a direct method of extracting the exponents from the matrix elements in more general cases. {copyright} {ital 1997} {ital The American Physical Society}
