Phase diagram of the two-dimensional Coulomb gas: A thermodynamic scaling Monte Carlo study
- School of Chemical Engineering, Cornell University, Ithaca, New York 14853-5201 (United States)
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{endash}Thouless insulator/conductor transition line and the first-order vapor{endash}liquid coexistence curve. The Kosterlitz{endash}Thouless line terminates at the first-order coexistence curve close to the gas{endash}liquid critical point. Our estimate of the vapor{endash}liquid critical point is, {ital T}{asterisk}{approx_equal}0.056, {rho}{asterisk}{approx_equal}0.21, in only modest agreement with previous theoretical estimates and semiquantitative numerical results. {copyright} {ital 1996 American Institute of Physics.}
