Kinetic energy driven pairing
Th. A. Maier, M. Jarrell, A. Macridin +1
Pairing occurs in conventional superconductors through a reduction of the electronic potential energy accompanied by an increase in kinetic energy, indicating that the transition i…
On the origin of the pseudogap in underdoped cuprates
Th. A. Maier, M. Jarrell, A. Macridin +1
We investigate the microscopic origin of the pseudogap in the weakly doped 2D Hubbard model using Quantum Monte Carlo within the dynamical cluster approximation. We compare our res…
Two Quantum Cluster Approximations
Th. A. Maier, O. Gonzalez, M. Jarrell +1
We provide microscopic diagrammatic derivations of the Molecular Coherent Potential Approximation (MCA) and Dynamical Cluster Approximation (DCA) and show that both are Phi-derivab…
Zinc Impurities in the 2D Hubbard model
Th. A. Maier, M. Jarrell
We study the two-dimensional Hubbard model with nonmagnetic Zn impurities modeled by binary diagonal disorder using Quantum Monte Carlo within the Dynamical Cluster Approximation.…
