dc.description.abstractThe exact solution of the distorted Ising-Hubbard model for a diamond chain is obtained by means of transfer matrix method. Based on this solution the magnetic, thermal and concurrence properties of the system are studied. We discuss in detail the ground state varying values of Ising and Hubbard interaction couplings, hopping amplitude, magnetic field, chemical potential and get paramagnetic, ferromagnetic, antiferromagnetic and ferrimagnetic phases of the system. Plateaus in magnetization curves and several-peak structures of the specific heat curve for different values of Hamiltonian parameters are obtained. The dependence of concurrence in Hubbard dimers from chain parameters, external magnetic field and temperature are studied.pt_BR
