软介质中临界涨落的约束导致作用在约束面上的临界Casimir力。这种力的温度和几何依赖关系用普遍的标度函数来表征。提出了一种新的方法来确定薄膜的晶格模型蒙特卡罗模拟。该方法基于自由能差积分格式。我们对Ising和XY普适类的结果分别与经典二元液体混合物和4He润湿层的相应实验结果相比较。

英文摘要:
The confinement of critical fluctuations in soft media induces critical Casimir forces acting on the confining surfaces. The temperature and geometry dependences of such forces are characterized by universal scaling functions. A novel approach is presented to determine them for films via Monte Carlo simulations of lattice models. The method is based on an integration scheme of free energy differences. Our results for the Ising and the XY universality class compare favourably with corresponding experimental results for wetting layers of classical binary liquid mixtures and of 4He, respectively.
