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…
Semi-analytical solution of the Kondo model in a magnetic field
C. Slezak, S. Kehrein, Th. Pruschke +1
The single impurity Kondo model at zero temperature in a magnetic field is solved by a semi-analytical approach based on the flow equation method. The resulting problem is shown to…
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…
