Strong short-range interactions in one-dimensional proton conductor
The behaviour of one-dimensional proton conductor is investigated on the basis of orientational-tunnelling model. The previously proposed technique which permits the proton interactions to be taken into account in the zeroorder Hamiltonian, and is based on Green’s function’s expansion in terms o...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The behaviour of one-dimensional proton conductor is investigated on the
basis of orientational-tunnelling model. The previously proposed technique
which permits the proton interactions to be taken into account in the zeroorder
Hamiltonian, and is based on Green’s function’s expansion in terms
of irreducible Green’s function parts, is generalized. The Larkin equation for
the one-particle proton Green’s function is solved, while irreducible Larkin
part is calculated within the framework of the first order approximation. The
proton energy spectrum and chemical potential behaviour are investigated,
and the results are compared with the ones previously obtained in the
Hubbard-1 type approximation. |
