Two-dimensional spin-polarized hydrogen at zero temperature

The ground-state properties of spin polarized hydrogen H↓ in two di- mensions (2D) are obtained by means of diffusion Monte Carlo calculations. Us- ingthemostaccuratetodateabinitioH↓-H↓ interatomicpotentialwehave studied hydrogen gas phase, from the very dilute regime until densities above its freezing point. For very low densities, the equation of state of the gas can be described in terms of the gas parameter na2, where a is the s-wave scattering length in 2D. The solid phase in 2D has also been studied up to high pressures and the gas-solid phase transition determined using the double- tangent Maxwell construction
