Neel to spin-Peierls transition in the ground state of a quasi-1D Heisenberg model coupled to bond phonons
Pinaki Sengupta
The spin-Peierls transition in the ground state of a quasi-one-dimensional spin-1/2 Heisenberg model coupled to adiabatic bond phonons is studied using a quantum Monte Carlo (QMC)…

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…
