No clear solution emerges although the competitions at work are established. Using the real-space Hartree-Fock approximation, the magnetic phase diagram of a ﬁve-orbital Hubbard model for the iron-based superconductors is studied varying the electronic density n in the range from ﬁve to seven electrons per transition metal atom. The Hubbard interaction U is also varied, at a ﬁxed Hund coupling J/U= 0.25.

The European Physical Society (EPS) is a not for profit association whose members include 41 National Physical Societies in Europe, individuals from all fields of physics, and European research institutions. Our main results are the full phase diagrams for 2D t − t′ − U Hubbard model for t′ = 0 and t′ = −0.35t in Figs. 1 and 2, respectively. They were obtained for a system size so large that they are practically identical with the thermodynamic limit.

The phase diagram of this system at zero tem- perature includes a superfluid phase and a Mott-insulator one, separated by a quantum phase transition. In 1998 it The ground state phase diagram of the weakly coupled extended Hubbard model with intraatomic attraction has been derived with the Hartree theory formulated We establish the phase diagram of the disordered three-dimensional Bose- Hubbard model at unity filling which has been controversial for many years.

The Mott-Hubbard metal-insulator transition in the paramagnetic phase of the one-band Hubbard model has long been used to describe similar features in real materials like V 2 O 3. In this Letter we investigate the antiferromagnetic phase of this model with frustration. 2001-12-10 · Phase diagram of a disordered boson Hubbard model in two dimensions. Lee JW(1), Cha MC, Kim D.

We study the zero-temperature phase transition of a two-dimensional disordered boson Hubbard model.

Ōno and R. Bulla and A. Hewson}, journal={The European Physical Journal B - Condensed Matter and Complex Systems}, year={2001}, volume={19}, pages={375-384} } We examine the zero- and finite-temperature phase diagrams of soft-core bosons of the extended Bose-Hubbard model on a square optical lattice. To study various quantum phases and their transitions we employ single-site and cluster Gutzwiller mean-field theory. We have observed that the Mott insulator phase vanishes above a critical value of nearest-neighbor interaction and the supersolid phase Phase diagrams of the disordered Bose-Hubbard model with cavity-mediated long-range and nearest-neighbor interactions?
