Competing inhomogeneous orders are a central feature of correlated electron materials,
including the high-temperature superconductors. The two-dimensional Hubbard model …

The insulator–metal transition remains among the most studied phenomena in correlated
electron physics. However, the spontaneous formation of spatial patterns amidst insulator …

We study the superconducting pairing correlations in the ground state of the doped Hubbard
model—in its original form without hopping beyond nearest neighbor or other perturbing …

We review nonperturbative numerical calculations on dynamical properties of the two-
dimensional Hubbard model and their relevance to various spectroscopic experiments on …

The discovery of different phases as a result of correlations, especially in low-dimensional
materials, has been always an exciting and fundamental subject of research. Recent …

We investigate the momentum-resolved spin and charge susceptibilities, as well as the
chemical potential and double occupancy in the two-dimensional Hubbard model as …

We explore the momentum-sector-selective metal-insulator transitions recently found in the
eight-site dynamical cluster approximation to the two-dimensional Hubbard model. The …

The dual-fermion approach offers a way to perform diagrammatic expansion around the
dynamical mean field theory. Using this formalism, the influence of antiferromagnetic …

Motivated by significant discrepancies between experimental observations of electron-
doped cuprates and numerical results of the Hubbard and tJ models, we investigate the role …

For doped two-dimensional Mott insulators in their normal state, the challenge is to
understand the evolution from a conventional metal at high doping to a strongly correlated …
