RESUMO

This work proposes two variational wave functions based on the concept of shadow particles that describes the solid phase of systems formed by atoms of 4He. One of them, called Periodic Free Shadow Wave Function (PFS) provides good results for this phase like the energies of the system and the Radial Distribution Function that proved to be in good agreement with other results of the literature. The other, called the Periodic Shadow Wave Function (PS) in addition to providing good results for these properties, describes the supersolid phase and thus predicts a Bose-Einstein Condensation of the solid phase. All the results that have been obtained are due to our own numerical implementations of the Variational Monte Carlo method
