Abstract: FIELD: physics of polaritons.  
     SUBSTANCE: invention relates to the physics of polaritons and Bose-Einstein condensates; creation and development of new approaches to solving complex computational problems using simulators based on systems of coupled polariton condensates. In particular, the present invention consists in the development of a system for selectively monitoring the interaction between the nearest nodes (condensates) in a fixed two-dimensional lattice of Bose condensates and the next nearest nodes without changing the geometry of the lattice and the intensity of the radiation exciting the condensates. The developed system is based on the principle based on the use of weak laser beams that modify the potential landscape for polaritons. This approach ensures high-precision control of the phase of the complex interaction of Bose condensates, which has been successfully demonstrated on arrays up to 16 nodes. It is extremely important that optically induced potential barriers make it possible to selectively control the interaction not only between the nearest sites (condensates) but also the next nearest sites in the lattice. Thus, a continuous transition from the antiferromagnetic phase to the ferromagnetic phase, and then to the phase with pair magnetization, is achieved by the all-optical method on the polariton platform. 
     EFFECT: present method of precise control of the relative phases of Bose condensates allows one to study various spin states in solid state physics and simulate processes in universal spin models with well-defined problem conditions.
