Dynamical susceptibilities in strong coupling approach
A. M. Shvaika
A general scheme to calculate dynamical susceptibilities of strongly correlated electron systems within the dynamical mean field theory is developed. Approach is based on an expans…

Strong-coupling approach for strongly correlated electron systems
A. M. Shvaika
A perturbation theory scheme in terms of electron hopping, which is based on the Wick theorem for Hubbard operators, is developed. Diagrammatic series contain single-site vertices…
