Proximity of the Superconducting Dome and the Quantum Critical Point in the Two-Dimensional Hubbard Model
Shu-Xiang Yang, Herbert Fotso, Shi-Quan Su +6
We use the dynamical cluster approximation to understand the proximity of the superconducting dome to the quantum critical point in the two-dimensional Hubbard model. In a BCS form…

Effect of long-range hopping on Tc in a two-dimensional Hubbard-Holstein model of the cuprates
E. Khatami, A. Macridin, M. Jarrell
We study the effect of long-range hoppings on Tc for the two-dimensional (2D) Hubbard model with and without Holstein phonons using parameters evaluated from band-structure calcula…
