Holographic Entanglement of a Big Bang Observable Universe

A. Bayne, K. R. S. Seshadri, M. A. Shafieh

Comments:

We study the holographic entanglement entropy of a big bang observable universe, which is the entropy of quantum fields in the universe. We derive the entropy of a big bang observable universe in two different holographic deterministic models. In the first model we find the entropy of the big bang observable universe in the big bang phase, which is the phase where the universe is accelerated in the Big Bang. In the second model we compute the entropy of the big bang observable universe in the big bang phase, which is the phase where the universe is accelerated in the Big Bang. In the case where the Big Bang particle is a particle decaying in a particle-hole, we find that the entropy is the same as in the particle-hole model, i.e., the entropy in the particle-hole model is the same as the entropy in the big bang model.

Quantise the impact of a non-perturbative parameter on the momentum of the weak gravity model

A. Bayne, J. J. Oost, A. R. van Hove

Comments:

In this letter we discuss the impact of a non-perturbative parameter of the weak gravity model on the momentum of photons in a Coulomb gas environment. In particular we discuss the impact of the non-perturbative parameter on the momentum of photons, which is typically defined by the mass of the dark photon and the energy density of the light photon. We derive the linearized momentum of photons in the weak gravity model and discuss the consequences for the dynamics of the weak gravity model.
