Sažetak
The ground-state properties of spin-polarized deuterium (D$\downarrow$) at zero temperature are obtained by means of diffusion Monte Carlo calculations within the fixed-node approximation. Three D$\downarrow$ species have been investigated (D$\downarrow_1$, D$\downarrow_2$, D$\downarrow_3$), corresponding respectively to one, two and three equally occupied nuclear spin states. Influence of the backflow correlations on the ground state energy of the systems is explored. The equations of state of liquid D$\downarrow_2$ and D$\downarrow_3$ are obtained and compared with the ones obtained in previous approximate predictions. The density and pressure at which D$\downarrow_1$ experiences a gas-liquid transition at $T$=0 are obtained.
