Influence of the interaction potential on the D/downarrow/1 equation of state

The ground-state properties of spin-polarized deuterium with only one occupied nuclear spin state (D$\downarrow_1$) at zero temperature are studied by means of the variational Monte Carlo (VMC) method. Influence of the backflow correlations on the ground-state energy of this Fermi system under investigation is also explored. The calculations have been performed using several interatomic potentials and the quantum phase of the D$\downarrow_1$ system is discussed. Our results are compared with other previously reported variational results.
