Ground-state properties of multicomponent Falicov–Kimball-like models I
We consider a classical lattice gas that consists of more than one “species” of particles (like a spin-32 Ising model or the atomic limit of the extended Hubbard model), whose ground-state phase diagram is macroscopically degenerate. This gas is coupled component-wise and in the Falicov–Kimball-like manner to a multicomponent free-fermion gas. We show rigorously that a component-wise coupling o...
متن کاملGround-state properties of two-dimensional dimerized Heisenberg models
J. Sirker, ∗ A. Klümper, † and K. Hamacher ‡ Theoretische Physik I, Universität Dortmund, Otto-Hahn-Str. 4, D-44221 Dortmund, Germany (Dated: February 1, 2008) The purpose of this paper is to investigate the ground-state properties of two-dimensional Heisenberg models on a square lattice with a given dimerization. Our aim is threefold: First, we want to investigate the dimensional transition fr...
متن کاملGround-state properties of tubelike flexible polymers.
In this work we investigate the structural properties of native states of a simple model for short flexible homopolymers, where the steric influence of monomeric side chains is effectively introduced by a thickness constraint. This geometric constraint is implemented through the concept of the global radius of curvature and affects the conformational topology of ground-state structures. A syste...
متن کاملBounding ground state energy of Hopfield models
In this paper we look at a class of random optimization problems that arise in the forms typically known as Hopfield models. We view two scenarios which we term as the positive Hopfield form and the negative Hopfield form. For both of these scenarios we define the binary optimization problems that essentially emulate what would typically be known as the ground state energy of these models. We t...
متن کاملLifting/lowering Hopfield models ground state energies
In our recent work [9] we looked at a class of random optimization problems that arise in the forms typically known as Hopfield models. We viewed two scenarios which we termed as the positive Hopfield form and the negative Hopfield form. For both of these scenarios we defined the binary optimization problems whose optimal values essentially emulate what would typically be known as the ground st...
