Danani, Andrea and Rasetti, Mario (1992) Dynamical symmetry of a dimer clifford mean-field extended Falicov-Kimball model. Modern Physics Letters B, 6 (25). pp. 1583-1592. ISSN 0217-9849
Full text not available from this repository.Abstract
In this paper, resorting to the Fermi-linearization technique, implemented for a two-site (dimer) cluster, the authors study the structure of dynamical symmetry which the use of Grassmann-Clifford mean-fields leads to, in the case of an extended Falicov-Kimball model. The resulting scheme to diagonalize the Hamiltonian is also discussed.
