摘要翻译:
我们研究了一般几何条件下介质之间的热Casimir和量子非延迟Lifshitz相互作用。我们将经典配分函数的计算映射到行列式上,并借助Cholesky分解对行列式进行离散和求值。通过对一组相互作用偶极子的路径积分量子化处理量子配分函数,并将其归结为行列式的乘积。我们将成对可加性和接近力的近似与我们的数值方法进行了比较。我们提出了一种“因式分解近似”,它在我们研究的几何中给出了相当好的数值结果。

英文摘要:
We study thermal Casimir and quantum non-retarded Lifshitz interactions between dielectrics in general geometries. We map the calculation of the classical partition function onto a determinant which we discretize and evaluate with the help of Cholesky factorization. The quantum partition function is treated by path integral quantization of a set of interacting dipoles and reduces to a product of determinants. We compare the approximations of pairwise additivity and proximity force with our numerical methods. We propose a ``factorization approximation'' which gives rather good numerical results in the geometries that we study.
