Variational study of the spin-gap phase of the one-dimensional t-J model
(American Physical Society, 1996-10-01)
We propose a correlated spin-singlet-pair wave function to describe the spin-gap phase of the one-dimensional t-J model at low density and large J/t. In addition to having singlet pairs, this wave function has a Jastrow ...
Choice of dispersion relation to calculate the QCD correction to Gamma(H->l(+)l(-))
(American Physical Soc, 1996-02-01)
We use the Operator Product Expansion (OPE) of quark vacuum polarization functions to show that the dispersion relation of Kniehl and Sirlin will yield the correct result to all orders in αs when applied to the QCD correction ...
