标题： The rapid-turn inflationary attractor

摘要： 我们证明了一类广义的快速转动双场膨胀吸引子解的存在性。仅要求一个大的、缓慢变化的转动速率，我们就完全解出了该系统，并且证明了该解的线性稳定性。一些近期研究过的转动膨胀模型，包括超膨胀、偏离膨胀以及平坦场空间模型，最终被归为这一广义吸引子解的特例。非常快速转动的模型尤其引人关注，因为它们可以与沼泽地猜想相兼容，我们还表明在这种极限情况下解会进一步简化。 显示英文摘要

摘要： We prove the existence of a general class of rapidly turning two-field inflationary attractors. By only requiring a large, slowly varying turn rate, we solve the system completely without specifying any metric or potential, and prove the linear stability of the solution. Several recently studied turning inflation models, including hyperinflation, side-tracked inflation, and a flat field-space model, turn out to be examples of this general class of attractor solutions. Very rapidly turning models are of particular interest since they can be compatible with the swampland conjectures, and we show that the solutions further simplify in this limit.
