- W2022958895 abstract "We calculate $2{k}_{F}$ and $4{k}_{F}$ charge-density wave (CDW) and spin-density wave (SDW) autocorrelation functions for the one-dimensional Hubbard model using a computer renormalization-group technique previously developed by us. We describe the method and expected accuracy of the results. The correlation functions are calculated for Hubbard parameter $frac{U}{t}=2,10,50$ and for two different band fillings. We obtain, describe, and compare for the first time the magnitudes and temperature dependences of the correlation functions. We find, inter alia, that the $4{k}_{F}$ instability arises at very large $U$ and that the $2{k}_{F}$ SDW and $4{k}_{F}$ CDW dominate at large $U$." @default.
