Abstract

In this work, we report results for the phase diagram of the two-dimensional Coulomb system. We use a recently proposed simulation method, thermodynamic scaling Monte Carlo, to determine the Kosterlitz-Thouless insulator/conductor transition line and the first-order vapor-liquid coexistence curve. The Kosterlitz-Thouless line terminates at the first-order coexistence curve close to the gas-liquid critical point. Our estimate of the vapor-liquid critical point is, T*≈0.056, p*≈0.21, in only modest agreement with previous theoretical estimates and semiquantitative numerical results.
