Many-Electron Atoms,, biology and condensed matter physics by using density functional theory (DFT), introduced in pioneering works [1, 2]. This approach is used as a basis for ab initio calculations for complex molecular systems and the details of the method are presented in numerous monographs and reviews [3–6].

Applications of OM for One-Dimensional Systems,The extended analysis of various physical problems related to anharmonic oscillator performed in previous chapter makes it possible to sort out the capabilities of the operator method, which are not exclusively related to QAO and can be exploited for description of more complex quantum systems.

Operator Method for Quantum Statistics,The construction of the uniformly available approximation (UAA) for thermodynamical functions has two specific features, which differ it from the solution of the Schr?dinger equation for stationary states. First of all, these functions depend both on Hamiltonian parameters and on the temperature ..
