Competition between charge-density-wave and superconducting orders on eight-leg square Hubbard cylinders
The study investigates how charge-density-wave (CDW) and superconducting (SC) orders compete in eight-leg square Hubbard cylinders. It finds that CDW often dominates, while SC correlations depend on the hopping term t'. The results show that the strength of CDW and SC orders are linked, leading to uncertainty about the phase diagram in this region.
