Inflation as a One-Loop Effect : [Abstract] / A.Arbuzov, D.Kuznetsov, B.Latosh, V.Shmidt // Физика элементарных частиц и атомного ядра. Письма. – 2024. – Т. 21, № 3. – C. 568. – URL: http://www1.jinr.ru/Pepan_letters/panl_2024_3/44_Arbuzov_ann.pdf.

We present an explicit example of a simple inflationary scenario where the accelerated expansion arises solely from quantum effects. We examine the most basic scalar-tensor gravity model with a single massive scalar field. Quantum gravity generates an effective scalar field potential that drives inflation. The model has the tensor-to-scalar ratio and scalar spectrum tilt consistent with the latest data for N > 64 e-foldings and the scalar field mass of order 2/3 Planck mass. We apply the same analysis for models with nonminimal couplings to gravity and find them strongly disfavored.
