Coupled Hubbard ladders at weak coupling: Pairing and spin excitations
Thomas A. Maier, Elbio Dagotto
The Hubbard model provides a simple framework in which one can study how certain aspects of the electronic structure of strongly interacting systems can be tuned to optimize the su…
Superconductivity in the bilayer Hubbard model: Are two Fermi surfaces better than one?
Seher Karakuzu, Steven Johnston, Thomas A. Maier
Fully occupied or unoccupied bands in a solid are often considered inert and irrelevant to a material's low-energy properties. But the discovery of enhanced superconductivity in he…
Intertwined spin, charge and pair correlations in the two-dimensional Hubbard model in the thermodynamic limit
Peizhi Mai, Seher Karakuzu, Giovanni Balduzzi +2
The high-temperature superconducting cuprates are governed by intertwined striped magnetic and charge orders in addition to superconductivity. Remarkably similar behavior has also…
Dynamical Cluster Approximation Study of Electron Localization in the Extended Hubbard Model
Hanna Terletska, Sergei Iskakov, Thomas Maier +1
We perform a detailed study of the phase transitions and mechanisms of electron localization in the extended Hubbard model using the dynamical cluster approximation on a $2\times 2…
Pairing correlations in the cuprates: a numerical study of the three-band Hubbard model
Peizhi Mai, Giovanni Balduzzi, Steven Johnston +1
We study the three-band Hubbard model for the copper oxide plane of the high-temperature superconducting cuprates using determinant quantum Monte Carlo and the dynamical cluster ap…
