The phase diagram of a two-dimensional core-softened system with purely repulsive monotonic potential

The phase diagram of a two-dimensional system with purely repulsive monotonic potential is studied by means of molecular dynamics method. It is shown that the system demonstrates a set of ordered phases, including such phases as dimers, oblique crystal and Kagome phase. The regions of stability of all ordered phases in the system is calculated. The scenarios of melting of triangular and square crystals of the system are identified.
