Dynamical renormalization group methods in theory of eternal inflation
Dmitry I. Podolsky
Dynamics of eternal inflation on the landscape admits description in terms of the Martin-Siggia-Rose (MSR) effective field theory that is in one-to-one correspondence with vacuum d…
On the stability of spherically symmetric spacetimes in metric f(R) gravity
Kimmo Kainulainen, Daniel Sunhede
We consider stability properties of spherically symmetric spacetimes of stars in metric f(R) gravity. We stress that these not only depend on the particular model, but also on the…
The Scalar Field Kernel in Cosmological Spaces
Jurjen F. Koksma, Tomislav Prokopec, Gerasimos I. Rigopoulos
We construct the quantum mechanical evolution operator in the Functional Schrodinger picture - the kernel - for a scalar field in spatially homogeneous FLRW spacetimes when the fie…
Spherically symmetric spacetimes in f(R) gravity theories
Kimmo Kainulainen, Johanna Piilonen, Vappu Reijonen +1
We study both analytically and numerically the gravitational fields of stars in f(R) gravity theories. We derive the generalized Tolman-Oppenheimer-Volkov equations for these theor…
The interior spacetimes of stars in Palatini f(R) gravity
Kimmo Kainulainen, Vappu Reijonen, Daniel Sunhede
We study the interior spacetimes of stars in the Palatini formalism of f(R) gravity and derive a generalized Tolman-Oppenheimer-Volkoff and mass equation for a static, spherically…
Covariant generalization of cosmological perturbation theory
Kari Enqvist, Janne Hogdahl, Sami Nurmi +1
We present an approach to cosmological perturbations based on a covariant perturbative expansion between two worldlines in the real inhomogeneous universe. As an application, at an…
