Pseudopotential Calculations

Single electron band structure techniques have been applied successfully to the interpretation of the near edge structures of metals and other materials. Among various band theories, the linear combination of atomic orbital (LCAO) method is especially simple and interpretable. The commonly used empirical LCAO method is mainly an interpolation method, where the energies and wave functions of atomic orbitals are adjusted in order to fit experimental or more accurately determined electron states. To achieve better accuracy, the size of calculation has to be expanded, for example, to include excited states and more-distant-neighboring atoms. This tends to sacrifice the simplicity and interpretability of the method.In this paper. we adopt an ab initio scheme which incorporates the conceptual advantage of the LCAO method with the accuracy of ab initio pseudopotential calculations. The so called pscudo-atomic-orbitals (PAO's), computed from a free atom within the local-density approximation and the pseudopotential approximation, are used as the basis of expansion, replacing the usually very large set of plane waves in the conventional pseudopotential method. These PAO's however, do not consist of a rigorously complete set of orthonormal states.

Goal. The purpose of this work is to analyze the norms of the current labor legislation regarding the regulation of the relations between the employee and the employer in the introduction of any restrictions and anti-epidemic measures in the conditions of national quarantine and prevention in such conditions of violations of labor rights of employees. It is important that during the course of the COVID-19 coronary pandemic measures, they were not only effective but also violated human rights, including work. Method. The methodology includes a comprehensive analysis and generalization of available scientific and theoretical material, experience of foreign countries and formulation of relevant conclusions and recommendations. During the research the following methods of scientific knowledge were used: terminological, comparative, functional, system-structural, logical-normative. Results. During the research it was found that the Ukrainian legislature, including foreign experience, was able to respond promptly to the quarantine situation by adopting anti-crisis laws, which did not neglect labor legislation. This is understandable, because in connection with the announcement of quarantine in the whole territory of Ukraine, employers had to make personnel decisions, and the current legislative framework did not clearly regulate the issues that arose. Scientific novelty. The study found that the updating of labor legislation in the area of labor relations regulation during the national quarantine period allows the employer to use certain forms of labor organization, in which the basic labor rights and guarantees of employees can be preserved. Practical importance. The results of the study can be used in law-making and law enforcement activities, as well as by employers in regulating labor relations with employees during the quarantine period.
