Pseudospin-electron model in the self-consistent gaussian fluctuation approximation
Pseudospin-electron model with an effective many-body interaction between pseudospins via conducting electrons is investigated within the generalized random phase approximation scheme with the self-consistent inclusion of mean field type contributions (coming from the effective pseudospin intera...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Pseudospin-electron model with an effective many-body interaction between
pseudospins via conducting electrons is investigated within the generalized
random phase approximation scheme with the self-consistent inclusion
of mean field type contributions (coming from the effective pseudospin
interaction) as well as gaussian fluctuations of the mean field (which
makes it possible to obtain more accurate results in the vicinity of the critical
points). Using the approach proposed here, the expressions are obtained
for the pseudospin correlation function, for pseudospin mean value, as well
as for the grand canonical potential. |
