In the spirit of the present treatment, we shall not address the most advanced problems of many-body perturbation theory (MBPT). Rather, the forthcoming chapter offers a simple introduction permitting one to pick up the basis ideas of MBPT. In particular, we shall derive the second-order ...
In this paper we present a method of incorporating spin-adapted configurations in a Many-Body Perturbation Theory (MBPT) framework. It has been demonstrated how the use of doubly excited Serber-type spinadapted configurations leads in a straightforward way to a well-defined MBPT series which in ...
In order to solve the A-body Schrödinger equation both accurately and efficiently for open-shell nuclei, a novel many-body method coined as Bogoliubov many-body perturbation theory (BMBPT) was recently formalized and applied at low orders. Based on the breaking of U(1) symmetry associated wi...
Correlation contributions to the multipole moments and frequency dependent polarizabilities of molecules are described within the framework of time‐dependent coupled Hartree–Fock and many‐body perturbation theory. Computationally feasible expressions are given for the ''true'' correlation contributions to th...
