On the Cosmological Constant-Graviton Mass correspondence

Oem Trivedi, Abraham Loeb

Relations between the graviton mass and the cosmological constant have led to some interesting implications. We show that in any approach which leads to a direct correlation be…

Rips and regular future scenario with Holographic Dark Energy: A comprehensive look

I. Brevik, Maxim Khlopov, S. D. Odintsov +2

Interest on the possible future scenarios the universe could have has grew substantially with breakthroughs on late-time acceleration. Holographic dark energy (HDE) presents a very…

A long freeze is hard to achieve in the presence of matter

Samuel Blitz, Robert J. Scherrer, Oem Trivedi

Certain holographic dark energy (HDE) models allow for the possibility of a ``long freeze,'' in which the scale factor evolves to a constant in the long-time limit. Here we extend…

Kantowski-Sachs cosmological model with axion-like scalar field and dark energy

Maxim Krasnov, Oem Trivedi, Maxim Khlopov

We consider Axion-like particle (ALP) model to construct numerical spatially homogeneous anisotropic Kantowski-Sachs cosmological model. We present various analytical and numerical…

The long freeze: an asymptotically static universe from holographic dark energy

Samuel Blitz, Robert J. Scherrer, Oem Trivedi

We show that some holographic dark energy models can lead to a future evolution of the universe in which the scale factor is asymptotically constant, while $\dot a \rightarrow…

Fractional Holographic Dark Energy

Oem Trivedi, Ayush Bidlan, Paulo Moniz

Holographic dark energy theories present a fascinating interface to probe late-time cosmology, as guided by contemporary ideas about quantum gravity. In this work, we present a new…

Landauer's principle and information at the cosmological horizon

Oem Trivedi

We show that the information loss at the cosmological apparent horizon in an expanding universe does not obey Landauer's principle for efficient information erasure. This is in con…

Holographic dark energy with Granda-Oliveros cutoff and ansatz based approach: An extended look

Oem Trivedi, Maxim Khlopov

Holographic dark energy models have proven to be a very interesting way to study various aspects of late-time acceleration of the universe. In this work we extensively study HDE mo…

New perspectives on future rip scenarios with holographic dark energy

Oem Trivedi, Robert J. Scherrer

We explore the asymptotic future evolution of holographic dark energy (HDE) models, in which the density of the dark energy is a function of a cutoff scale . We develop a genera…

Tsallis holographic dark energy with power law ansatz approach

Oem Trivedi, Maxim Khlopov, Alexander V. Timoshkin

Holographic principles have proven to be a very interesting approach towards dealing with the issues of the late-time acceleration of the universe, which has resulted in a great am…

On rips and cosmological singularities in a universe merging with baby universes

Oem Trivedi, Maxim Khlopov

Understanding the late-time acceleration of the universe and its subtleties is one of the biggest mysteries in cosmology. A lot of different approaches have been put forward to dea…
