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…

Role of the van Hove Singularity in the Quantum Criticality of the Hubbard Model
K. -S. Chen, S. Pathak, S. -X. Yang +5
A quantum critical point (QCP), separating the non-Fermi liquid region from the Fermi liquid, exists in the phase diagram of the 2D Hubbard model [Vidhyadhiraja et. al, Phys. Rev.…
