论文摘要
超流卷（USR）通胀中的非吸引者进化会导致超级弯曲曲率扰动的放大，然后诱导强大而可检测的随机重力波背景。在这封信中，我们从第三个Ligo-Virgo观察运行中的数据中搜索了这样的随机重力波背景，并将约束放在USR通货膨胀模型上。在95％的置信度下，USR阶段的$ e $ fold数字被约束为$Δn\ Lessim 2.9 $，并且在USR期间放大的曲率扰动的功率谱限制为$ \ log_ {10} p_ {10} p_ {r \ mathrm {r \ mathrm {p} p} p} <-1.7 $ 110 〜\ Mathrm {PC^{ - 1}} \ Lessim K \ Lessim 1.7 \ times10^{11}〜\ Mathrm {PC^{ - 1}} $。此外，我们预测了未来实验限制USR通货膨胀的能力，并找到$ p_ {r \ mathrm {p}} \ Lessim 10^{ - 3.6} $ for Lisa and Taiji，$ P_ $ p_ {r \ mathrm {p}} \ Lessim 10^{ - 5.5} $用于DECIGO和BIG BANG观察者，$ P_ {R \ Mathrm {p}} \ lyssim 10^{ - 5.2} $ for Square kilome arnay的$。
The nonattractor evolution in ultra-slow-roll (USR) inflation results in the amplification of superhorizon curvature perturbations and then induces a strong and detectable stochastic gravitational wave background. In this letter, we search for such a stochastic gravitational wave background in data from the third LIGO-Virgo observing run and place constraints on the USR inflationary models. The $e$-folding number of the USR phase are constrained to be $ΔN \lesssim 2.9$ at the 95% confidence level and the power spectrum of curvature perturbations amplified during the USR phase is constrained to be $\log_{10}P_{R\mathrm{p}}<-1.7$ at the scales $2.9\times10^5 ~\mathrm{pc^{-1}} \lesssim k \lesssim 1.7\times10^{11}~\mathrm{pc^{-1}}$. Besides, we forecast the ability of future experiments to constrain USR inflation, and find $P_{R\mathrm{p}}\lesssim 10^{-3.6}$ for LISA and Taiji, $P_{R\mathrm{p}}\lesssim 10^{-3.3}$ for Cosmic Explore and Einstein Telescope, $P_{R\mathrm{p}}\lesssim 10^{-5.5}$ for DECIGO and Big Bang Observer and $P_{R\mathrm{p}}\lesssim 10^{-5.2}$ for Square Kilometre Array.
