On the solution of a supersymmetric model of correlated electrons
We consider the exact solution of a model of correlated electrons based on the super-algebra Osp(2|2). The corresponding Bethe ansatz equations have an interesting form. We derive an expression for the ground state energy at half filling. We also present the eigenvalue of the transfer matrix commuting with the Hamiltonian.

متن کاملNew Supersymmetric and Exactly Solvable Model of Correlated Electrons.
A new lattice model is presented for correlated electrons on the unrestricted 4-dimensional electronic Hilbert space ⊗n=1C (where L is the lattice length). It is a supersymmetric generalization of the Hubbard model, but differs from the extended Hubbard model proposed by Essler, Korepin and Schoutens. The supersymmetry algebra of the new model is superalgebra gl(2|1). The model contains one sym...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
