Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

This article gives an overview of both theoretical and experimental developments
concerning states with lattice symmetry breaking in the cuprate high-temperature …

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

Proximity to a Mott insulating phase is likely to be an important physical ingredient of a
theory that aims to describe high-temperature superconductivity in the cuprates. Quantum …

We investigate the Hubbard model on the anisotropic triangular lattice as a suggested
effective description of the Mott phase in various triangular organic compounds. Employing …

Variational Monte Carlo is a many-body numerical method that scales well with system size.
It has been extended to study the Green function only recently by Charlebois and Imada …

The superfluid to Mott insulator transition in cavity polariton arrays is analyzed using the
variational cluster approach, taking into account quantum fluctuations exactly on finite length …

The nature of the metal-insulator Mott transition at zero temperature has been discussed for
a number of years. Whether it occurs through a quantum critical point or through a first-order …

Based solely on the analytical properties of the single-particle Green's function of fermions at
finite temperatures, we show that the generalized Luttinger theorem inherently possesses …

Motivated by the possibility of superconductivity in doped graphene sheets, we investigate
superconducting order in the extended Hubbard model on the two-dimensional graphene …
