WebThe basic properties of oscillons – localized, long-lived, time-dependent scalar field configurations – are briefly reviewed, including recent results demonstrating how their existence depends on the dimensionality of … WebOct 2, 2024 · gravity. In this work we study vacuum decay and bubble nucleation in models of higher curvature gravity. Building upon the analysis of Coleman-De Luccia (CDL), we present the formalism to calculate the Euclidean action and the bounce solution for a general gravity in the thin wall approximation. We calculate the size of the nucleated …
