    "abstract": "We present improved worldline numerical algorithms for high-precision\ncalculations of Casimir interaction energies induced by scalar-field\nfluctuations with Dirichlet boundary conditions for various Casimir geometries.\nSignificant reduction of numerical cost is gained by exploiting the symmetries\nof the worldline ensemble in combination with those of the configurations. This\nfacilitates high-precision calculations on standard PCs or small clusters. We\nillustrate our strategies using the experimentally most relevant sphere-plate\nand cylinder-plate configuration. We compute Casimir curvature effects for a\nwide parameter range, revealing the tight validity bounds of the commonly used\nproximity force approximation (PFA). We conclude that data analysis of future\nexperiments aiming at a precision of 0.1% must no longer be based on the PFA.\nRevisiting the parallel-plate configuration, we find a mapping between the\nD-dimensional Casimir energy and properties of a random-chain polymer ensemble.",
