标题： The rapid-turn inflationary attractor

摘要： 我们证明了一类快速转向的双场暴胀吸引子的存在性。 通过要求一个大而缓慢变化的转向速率以及存在一个守恒的绝热模式，我们完全解出了该系统，而无需指定任何度规或势能，并证明了该解的线性稳定性。 几种最近研究过的转向暴胀模型，包括超暴胀、偏离轨道的暴胀以及平坦场空间模型，被证明是这种一般吸引子解的例子。 非常快速转向的模型特别值得关注，因为它们可以与景观猜想相容，我们还表明在这一极限下解进一步简化。 显示英文摘要

摘要： We prove the existence of a general class of rapidly turning two-field inflationary attractors. By requiring a large, slowly varying turn rate and the existence of a conserved adiabatic mode, 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.
