The fascinating electronic properties of the family of layered organic molecular crystals
kappa-(BEDT-TTF) 2X where X is an anion (eg, X= I3, Cu [N (CN) 2] Br, Cu (SCN) 2) are …

High-resolution angle-resolved photoemission data from the insulating phase of the charge-
density-wave (CDW) material 1 T-TaS 2 reveal the backfolding of the electronic bands …

Motivated by the unconventional properties and rich phase diagram of Na x Co O 2 we
consider the electronic and magnetic properties of a two-dimensional Hubbard model on an …

We investigate the metal-insulator transition in the half-filled Hubbard model on the two-
dimensional triangular lattice using both the Kotliar-Ruckenstein slave-boson technique and …

We demonstrate theoretically that the electronic ground state of the potassium-covered Si
(111)-B surface is a Mott insulator, explicitly contradicting band theory but in good …

Un modèle de Hubbard sur un réseau triangulaire anisotrope rempli à moitié a été proposé
comme modèle minimal pour décrire les couches conductrices κ (BEDT TTF) 2X dans les …

Coherent driving has established itself as a powerful tool for guiding a many-body quantum
system into a desirable, coherent non-equilibrium state. A thermodynamically large system …

Motivated by the recent experimental studies on layered ferromagnetic metallic system GdI 2
and its doped variant GdI 2 H x we develop a model to understand their ground state …

We have studied the Hubbard model with bond-charge interaction on a triangular lattice for
a half-filled band. At the point of particle-hole symmetry the model could be analysed in …

We study the Hubbard model on the triangular lattice for general fillings by means of the
slave-boson technique. In particular, we consider the stability regions of the paramagnetic …
