    "abstract": "We obtain the equation of state of interacting alpha matter and the critical\ntemperature of Bose-Einstein condensation of alpha particles within an\neffective scalar field theory. We start from a non-relativistic model of\nuniform alpha matter interacting with attractive two-body and repulsive\nthree-body potentials and reformulate this model as a O(2) symmetric scalar\n\\phi^6 field theory with negative quartic and positive sextic interactions.\nUpon restricting the Matsubara sums, near the temperature of Bose-Einstein\ncondensation, to the zeroth order modes we further obtain an effective\nclassical theory in three spatial dimensions. The phase diagram of the alpha\nmatter is obtained from simulations of this effective field theory on a lattice\nusing local Monte-Carlo algorithms.",
