Solving the Parquet Equations for the Hubbard Model beyond Weak Coupling
Ka-Ming Tam, H. Fotso, S. -X. Yang +4
We find that imposing the crossing symmetry in the iteration process considerably extends the range of convergence for solutions of the parquet equations for the Hubbard model. Whe…

Dual Fermion Dynamical Cluster Approach for Strongly Correlated Systems
S. -X. Yang, H. Fotso, H. Hafermann +4
We have designed a new multi-scale approach for Strongly Correlated Systems by combining the Dynamical Cluster Approximation (DCA) and the recently introduced dual-fermion formalis…

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…
