Exact solution of the 1D Hubbard model with NN and NNN interactions in the narrow-band limit
Ferdinando Mancini, Evgeny Plekhanov, Gerardo Sica
We present the exact solution, obtained by means of the Transfer Matrix (TM) method, of the 1D Hubbard model with nearest-neighbor (NN) and next-nearest-neighbor (NNN) Coulomb inte…
Emery vs. Hubbard model for cuprate superconductors: a Composite Operator Method study
Adolfo Avella, Ferdinando Mancini, Francesco Paolo Mancini +1
Within the Composite Operator Method (COM), we report the solution of the Emery model (also known as p-d or three band model), which is relevant for the cuprate high-Tc superconduc…
Exact solution of the 1D Hubbard model in the atomic limit with inter-site magnetic coupling
F. Mancini, E. Plekhanov, G. Sica
In this paper we present for the first time the exact solution in the narrow-band limit of the 1D extended Hubbard model with nearest-neighbour spin-spin interactions described by…
The Composite Operator Method (COM)
Adolfo Avella, Ferdinando Mancini
The Composite Operator Method (COM) is formulated, its internals illustrated in detail and some of its most successful applications reported. COM endorses the emergence, in strongl…
Spin and charge orderings in the atomic limit of the U-V-J model
Ferdinando Mancini, Evgeny Plekhanov, Gerardo Sica
In this paper we study a generalization of the 1D Hubbard model by considering density-density and Ising-type spin-spin nearest neighbor (NN) interactions, parameterized by and…
Correlation-induced band suppression in the two-orbital Hubbard model
E Plekhanov, A Avella, F Mancini +1
The orbital degrees of freedom are of vital importance in explanation of various phenomena. Among them is the orbital-selective Mott transition (OSMT), which is thought to occur in…
