Evolution of the Superconductivity Dome in the two dimensional Hubbard Model
Kuang-Shing Chen, Zi Yang Meng, Shu-Xiang Yang +3
In a recent publication [Chen et al., Phys. Rev. B 86, 165136 (2012)], we identified a line of Lifshitz transition points separating the Fermi liquid and pseudogap regions in the h…
Magnetic anisotropy effects on quantum impurities in superconducting host
Rok Zitko, Oliver Bodensiek, Thomas Pruschke
We study the magnetic anisotropy effects on the localized sub-gap excitations induced by quantum impurities coupled to a superconducting host. We establish the ground-state phase d…
Anomaly in the heat capacity of Kondo superconductors
Rok Zitko, Thomas Pruschke
Using numerical renormalization group we study thermodynamic properties of a magnetic impurity described by the Anderson impurity model in a superconducting host material described…
Suppression of d-wave superconductivity in the checkerboard Hubbard model
D. G. S. P. Doluweera, A. Macridin, T. A. Maier +2
Using a dynamical cluster quantum Monte Carlo approximation we investigate the d-wave superconducting transition temperature in the doped 2D repulsive Hubbard model with a we…
Kondo screening in d-wave superconductors in a Zeeman field and implications for STM spectra of Zn-doped cuprates
Matthias Vojta, Robert Zitzler, Ralf Bulla +1
We consider the screening of an impurity moment in a d-wave superconductor under the influence of a Zeeman magnetic field. Using the Numerical Renormalization Group technique, we i…
d-wave Superconductivity in the Hubbard Model
Th. Maier, M. Jarrell, Th. Pruschke +1
The superconducting instabilities of the doped repulsive 2D Hubbard model are studied in the intermediate to strong coupling regime with help of the Dynamical Cluster Approximation…
