论文摘要
使用积分转换，获得了流体的统计场理论的现场理论哈密顿，并获得了哈密顿量系数的微观表达。将这种方法应用于液体蒸气界面，我们在温度，密度和分子间电位的参数方面得出了表面张力的显式分析表达。我们还证明，可以对整体转换中出现的形式统计领域进行明确的物理解释 - 它可能与一体局部微观潜力有关。该理论缺乏任何临时或拟合参数的结果与可用的仿真数据达成了很好的一致性。
Using the integral transformation, the field-theoretical Hamiltonian of the statistical field theory of fluids is obtained, along with the microscopic expressions for the coefficients of the Hamiltonian. Applying this approach to the liquid-vapor interface, we derive an explicit analytical expression for the surface tension in terms of temperature, density and parameters of inter-molecular potential. We also demonstrate that a clear physical interpretation may be given to the formal statistical field arising in the integral transformation - it may be associated with the one-body local microscopic potential. The results of the theory, lacking any ad-hoc or fitting parameters are in a good agreement with available simulation data.
