Non-Gaussianity in History-Dependent Gravity: Resonant Bispectrum and Violation of Maldacena Consistency

Year: 2026

Type: article

Abstract: Paper VII in the History-Dependent Gravity (HDG) series. We derive the primordial bispectrum in HDG, showing that the memory kernel generates resonant equilateral non-Gaussianity with amplitude f_NL ~ τ_K H. We identify a discovery window τ_K H ~ O(1-10) accessible to next-generation CMB experiments. We demonstrate a controlled violation of the Maldacena consistency relation in the squeezed limit, arising from nonlocal temporal dynamics. This work establishes connections to entropy production (Paper VIII) and baryogenesis (Paper IX).
