宏观物体之间的卡西米尔力很好理解，但物体内部的卡西米尔应力却不清楚。假设真空或均匀介质遇到软壁，其中折射率连续但其导数跳跃。对于这种情况，我们预测软壁内部及其边缘附近的应力的特征幂律。我们的结果表明，无论液体是被吸引还是被排斥，这种边缘在液体表面聚集时都是不被容忍的。
The Casimir force between macroscopic bodies is well understood, but not the Casimir stress inside bodies. Suppose empty space or a uniform medium meets a soft wall where the refractive index is continuous but its derivative jumps. For this situation we predict a characteristic power law for the stress inside the soft wall and close to its edges. Our result shows that such edges are not tolerated in the aggregation of liquids at surfaces, regardless whether the liquid is attracted or repelled.
