Microscopic density functional theory for dendrimers
Density functional theory for a simple model of dendrimers is proposed. The theory is based on fundamental measure theory, which accounts for the hard-sphere repulsion of the segments and on the Wertheim first-orde...

Green functions in the renormalized many-body perturbation theory for correlated and disodered electrons
We review utilization of Green functions in the process of renormalization of many-body perturbation theory so that the limits of strongly correlated and strongly disordered electrons be reliably described......

Many-body Brillouin-Wigner second-order perturbation theory: A robust and efficient approach to the multireference correlation problem
formula of second-order many-body perturbation theory (MBPT2), i.e. Moller-Plesset-specific multireference Rayleigh-Schrodinger-like perturbation theory. It is shown that multireference many-body Brillouin-Wigner ...

Expansions of tau hadronic spectral function moments in a nonpower QCD perturbation theory with tamed large order behavior
of moments in the standard fixed-order and contour-improved perturbation theories, we consider the perturbative behavior of these moments in the framework of a QCD nonpower perturbation theory, defined by...

Perturbation theory of quantum resonances
We propose a contribution to the theory of quantum resonances that combines complex absorbing potentials (CAP) with standard perturbation theory. We start from resolvents that depend on two variables, the complex energy z a...
