We study critical point finite-size effects in the case of the susceptibility of a film in which interactions are characterized by a van der Waals-type power law tail. The geometry is appropriate to a slablike system with two bounding surfaces. Boundary conditions are consistent with surfaces that both prefer the same phase in the low temperature, or broken symmetry, state. We take into account both interactions within the system and interactions between the constituents of the system and the material surrounding it. Specific predictions are made with respect to the behavior of 3He and 4He films in the vicinity of their respective liquid-vapor critical points.
我们研究了薄膜磁化率情况下的临界点有限尺寸效应，其中相互作用由范德瓦尔斯型幂律尾部表征。该几何形状适用于具有两个边界表面的板状系统。边界条件与在低温或破缺对称状态下都偏好相同相的表面一致。我们考虑了系统内部的相互作用以及系统组成部分与周围材料之间的相互作用。针对³He和⁴He薄膜在其各自液 - 气临界点附近的行为做出了具体预测。
