Functional Renormalization Group Analysis of the Half-filled One-dimensional Extended Hubbard Model
Ka-Ming Tam, Shan-Wen Tsai, David K. Campbell
We study the phase diagram of the half-filled one-dimensional extended Hubbard model at weak coupling using a novel functional renormalization group (FRG) approach. The FRG method…

Renormalization Group Approach to Strong-Coupled Superconductors
S. -W. Tsai, A. H. Castro Neto, R. Shankar +1
We develop an asymptotically exact renormalization group (RG) approach that treats electron-electron and electron-phonon interactions on equal footing. The approach allows an unbia…

Comment on ``Ground State Phase Diagram of a Half-Filled One-Dimensional Extended Hubbard Model''
A. W. Sandvik, P. Sengupta, D. K. Campbell
In Phys. Rev. Lett. 89, 236401 (2002), Jeckelmann argued that the recently discovered bond-order-wave (BOW) phase of the 1D extended Hubbard model does not have a finite extent in…
