The purpose of the project is active participation of five young specialists of ITP NSC KIPT in scientific research, which is currently held in the world-leading laboratories devoted to the studies of correlation phenomena in quantum gases in the presence of external laser fields. These spatial correlations play one of key roles in many aspects of modern science, including research fields from condensed matter physics to high-energy physics. At the same time, there is a challenge of systematic and reliable theoretical description originating from a large number of degrees of freedom in many-particle systems. Despite tremendous technological progress in computational possibilities, many of the current problems remain intractable for exact numerical analysis. Therefore, there is a need for the novel and more reliable methodology, which is based on both the development of new theoretical approaches and the increase of computational resources. Evolution of the spatial correlation length from microscales to a regime of a formation of ordered phases is one of the most impressive phenomena in condensed matter physics. Among the many-particle states of matter, the superconducting phase in solid-state materials is the most noticeable due to the incredible impact on technologies in case of a discovery of the room-temperature superconductors. At the same time, the most promising materials (cuprates) remain very difficult for systematic theoretical description from the first principles and modelling due to the influence of quantum spatial correlations on the physical properties of these materials. Thus, according to R. Feynmann, the more elegant alternative would be an employment of universal quantum simulators, which perfectly match for describing and modelling of quantum many-particle systems. In particular, the study of spatial correlations in potential quantum simulators of orbital and spin phenomena is proposed within the project as one of the main research directions.
