Warp Factory: A Numerical Toolkit for the Analysis and Optimization of Warp Drive Geometries

The last few decades of warp drive research have focused on analytic methods to explore warp solutions to Einstein's field equations. These analytic solutions tend to favor simple metric forms which are easier to analyze but limit the space of exploration. In addition, all solutions to date have involved unphysical qualities, such as negative energy, violation of energy conditions, or enormous energy requirements. In an effort to explore the space of physically meaningful warp drives, the Advanced Propulsion Laboratory (APL) at Applied Physics has developed Warp Factory, a toolkit written in MATLAB for numerically analyzing and optimizing warp drive geometries. Warp Factory consists of a series of three primary modules: the solver, the analyzer, and the optimizer. Together, these modules allow users to solve the Einstein field equations, compute energy conditions and scalars, and perturbatively optimize general metrics. Finally, the toolkit offers insightful 2D and 3D visualizations of general metrics and stress-energy tensors. The methods used in Warp Factory, along with their application in evaluating and optimizing common metrics, are discussed. With Warp Factory, APL hopes to accelerate warp research and bring us one step closer to physical and realizable warp drives.
