Mean field theory for the lattice gas
WebApr 19, 2024 · 1.1. Lattice Gas. Consider a lattice gas in which the particles occupy the sites of a d -dimensional lattice, with the constraint that each site cannot be occupied by more than one particle. Let e i equal a variable that takes values { 0, 1 }: 0 when is the site is vacant and 1 when it is occupied. The interaction energy of each configuration ... WebApr 11, 2024 · We theoretically investigate, within Schwinger-boson mean-field theory, the transition from a gapped Z 2 quantum spin liquid, in a J 1 − J 2 Heisenberg spin-1 2 system in a honeycomb lattice, to a chiral Z 2 spin-liquid phase under the presence of time-reversal symmetry-breaking scalar chiral interaction (with amplitude J χ).We numerically obtain a …

WebMar 3, 2024 · These models are of significance as they are equivalent to a mean-field theory of a lattice superconductor. To explicitly construct these solitons, we generalize supersymmetric quantum mechanics to tight-binding models. We show that a matrix transformation exists that maps a tight-binding model to an isospectral one which shares … WebThe Zeroth Approximation or Mean Field Solution For a lattice model of a liquid solution we distribute molecules of type 1 and type 2 over the lattice (without any further holes).
