We introduce an efficient technique for computing Casimir energies and forces between objects of arbitrarily complex 3D geometries. In contrast to other recently developed methods, our technique easily handles nonspheroidal, nonaxisymmetric objects, and objects with sharp corners. Using our new technique, we obtain the first predictions of Casimir interactions in a number of experimentally relevant geometries, including crossed cylinders and tetrahedral nanoparticles.
我们介绍了一种用于计算任意复杂三维几何形状物体之间卡西米尔能量和力的高效技术。与其他最近开发的方法不同，我们的技术能够轻松处理非球形、非轴对称物体以及带有尖角的物体。使用我们的新技术，我们首次预测了许多实验相关几何形状中的卡西米尔相互作用，包括交叉圆柱体和四面体纳米颗粒。
