Spin-resolved correlations at arbitrary spin polarization and ground state of a quasi-one-dimensional electron gas

► We have studied spin-resolved correlations and ground-state of a quasi-one-dimensional electron gas. ► Our results show a reasonable agreement with the diffusion Monte Carlo Simulations. ► We find, in agreement with experiments, an abrupt polarization transition below a critical density. ► The same-spin correlation energy can become little positive below a critical density.
