Asymmetric Diamond Ising-Hubbard Chain with Attraction
Section: General problems of theoretical physics
Original Author's Text: Ukrainian
Abstract: The ground state and thermodynamic properties of an asymmetric diamond Ising–Hubbard chain with the on-site electron-electron attraction has been considered. The problem can be solved exactly using the decoration-iteration transformation. In the case of the antiferromagnetic Ising interaction, the influence of this attraction on the ground state and the temperature dependences of the magnetization, magnetic susceptibility, and specific heat has been studied.
Key words: Ising–Hubbard chain, attraction, ground state, magnetization, specific heat.
