BRANECODE: A program for simulations of braneworld dynamics

Abstract We describe an algorithm and a C++ implementation that we have written and made available for calculating the fully nonlinear evolution of 5D braneworld models with scalar fields. Bulk fields allow for the stabilization of the extra dimension. However, they complicate the dynamics of the system, so that analytic calculations (performed within an effective 4D theory) are usually only reliable for static bulk configurations or when the evolution of the extra dimension is negligible. In the gene...

摘要 本文介绍了我们编写并公开的一套算法与C++实现程序，用于计算含标量场的五维膜世界（5D braneworld）模型的完全非线性演化。体场（bulk field）可实现额外维度（extra dimension）的稳定，但会使系统动力学复杂化，因此基于有效四维理论（effective 4D theory）开展的解析计算通常仅在静态体构型或额外维度演化可忽略时才可靠。在……
