Electronic Correlations within Fermionic Lattice Models
M. Matlak, B. Grabiec, S. Krawiec
We investigate two-site electronic correlations within generalized Hubbard model, which incorporates the conventional Hubbard model (parameters: (hopping between nearest neighb…
Magnetism and superconductivity within extended Hubbard model for a dimer. Exact results
B. Grabiec, S. Krawiec, M. Matlak
We find the eigenvalues and eigenvectors of the extended Hubbard dimer and we represent each part of the dimer Hamiltonian in the…
Fermi level and phase transformations in GdCo
K. Gatner, A. N. Lachinov, M. Matlak +2
We performed three independent measurements for a polycristalline, ferromagnetic sample in the temperature range from 300-440 K: chemical potential, current flow through t…
Hubbard Hamiltonian in the dimer representation. Large U limit
M. Matlak, J. Aksamit, B. Grabiec +1
We formulate the Hubbard model for the simple cubic lattice in the representation of interacting dimers applying the exact solution of the dimer problem. By eliminating from the co…
