The adsorbed atoms exhibit tendency to occupy a triangular lattice formed by periodic potential of the underlying crystal surface. Such a lattice is formed by, e.g., a single layer of graphane or the graphite surfaces as well as (111) surface of face-cubic center crystals. In the present work, an extension of the lattice gas model to S=1/2 fermionic particles on the two-dimensional triangular (hexagonal) lattice is analyzed. In such a model, each lattice site can be occupied not by only one…

The inhomogeneous distribution of charged particles is known as charge-order phenomena. Recent experimental studies of (quasi-) two-dimensional materials found different ordered patterns on the

Competition between charge and spin order in the t-U-V extended Hubbard model on the triangular lattice

Several new classes of compounds can be modeled in first approximation by electrons on the triangular lattice that interact through on-site repulsion U as well as nearest-neighbor repulsion V. This

Charge and spin order on the triangular lattice: NaxCoO2 at x=0.5.

An extended Hubbard model using a spatially unrestricted Gutzwiller approximation is studied and a new class of charge and spin ordered states are found at x=1/3 and x=0.5 where antiferromagnetic (AFM) frustration is alleviated via weak charge inhomogeneity.

Charge ordering and phase separation in the infinite dimensional extended Hubbard model

We study the extended Hubbard model with both on-site (U) and nearest neighbor (V) Coulomb repulsion using the exact diagonalization method within the dynamical mean field theory. For a fixed U

Diversity of charge orderings in correlated systems.

This work studies the zero-bandwidth limit of the extended Hubbard model, which can be considered as a simple effective model of charge ordered insulators and derives the exact ground state diagrams for different lattice dimensionalities.

Various Charge-Ordered States in the Extended Hubbard Model with On-Site Attraction in the Zero-Bandwidth Limit

The extended Hubbard model in the zero-bandwidth limit with intersite density–density interactions (nearest- and next-nearest-neighbor) is analyzed in the site-dependent mean-field approximation. In

Ground State Structure of Triangular Lattice Gas Model with up to 3rd Neighbor Interactions

The ground state of the triangular lattice gas model with up to 3rd neighbor interactions is investigated by use of the method of geometrical inequalities. The structure of the ground state at an

Patterns of striped order in the classical lattice Coulomb gas.

A simple regularity is found in the low-temperature charge configurations which consist of a suitable periodic combination of a few basic striped patterns characterized by the existence of partially filled diagonal channels.
