Probing primordial black holes with anisotropies in stochastic gravitational-wave background
Sai Wang, Valeri Vardanyan, Kazunori Kohri
Primordial black holes, if considered to constitute a significant fraction of cold dark matter, trace the inhomogeneous large-scale structure of the Universe. Consequently, the sto…
The Classical Symmetron Force in Casimir Experiments
Benjamin Elder, Valeri Vardanyan, Yashar Akrami +3
The symmetron is a typical example of screened modified gravity, wherein the symmetron force is dynamically suppressed in dense environments. This allows it to hide in traditional…
On nonlocally interacting metrics, and a simple proposal for cosmic acceleration
Valeri Vardanyan, Yashar Akrami, Luca Amendola +1
We propose a simple, nonlocal modification to general relativity (GR) on large scales, which provides a model of late-time cosmic acceleration in the absence of the cosmological co…
How can we tell whether dark energy is composed by multiple fields?
Valeri Vardanyan, Luca Amendola
Dark energy is often assumed to be composed by a single scalar field. The background cosmic expansion is not sufficient to determine whether this is true or not. We study multi-fie…
