Casimir操纵:涨落诱导力的方向依赖性

Casimir manipulations: The orientation dependence of fluctuation-induced forces

T. Emig, N. Graham, R. L. Jaffe, M. Kardar

摘要:

两个物体之间或物体与平面之间的卡西米尔相互作用取决于它们的相对方向。我们使这些角度依赖明确考虑长或扁球体。随着方向的变化是精确计算的电磁场在渐近大的距离,并在任意的分离的标量场。对于镜子前面的椭球体,主导项是方向无关的,并且我们从高阶计算中找到最佳方向。

英文摘要:

The Casimir interaction between two objects, or between an object and a plane, depends on their relative orientations. We make these angular dependences explicit by considering prolate or oblate spheroids. The variation with orientation is calculated exactly at asymptotically large distances for the electromagnetic field, and at arbitrary separations for a scalar field. For a spheroid in front of a mirror, the leading term is orientation independent, and we find the optimal orientation from computations at higher order.
