Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

Given the proliferation of bouncing models in recent years, we gather and critically assess
these proposals in a comprehensive review. The PLANCK data shows an unmistakably red …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

We hereby introduce and extensively study a class of non-polynomial higher derivative
theories of gravity that realize a ultraviolet (UV) completion of Einstein general relativity …

We reconstruct F (R) gravity models with exponential and power-law forms of the scale factor
in which bounce cosmology can be realized. We explore the stability of the reconstructed …

In this paper we will show all the linearized curvature tensors in the infinite derivative ghost
and singularity free theory of gravity in the static limit. We have found that in the region of …

In this paper we study the most general covariant action of gravity up to terms that are
quadratic in curvature. In particular this includes non-local, infinite derivative theories of …

We hereby review a class of quantum gravitational theories based on weakly nonlocal
analytic classical actions. The most general action is characterized by two nonpolynomial …

In this paper we will study Lorentz-invariant, infinite derivative quantum field theories, where
infinite derivatives give rise to non-local interactions at the energy scale M s, beyond the …

We examine the quantum gravitational entanglement of two test masses in the context of
linearized general relativity with specific nonlocal interaction with matter. To accomplish this …
