# Holographic Vacuum Energy

@article{Thomas2000HolographicVE, title={Holographic Vacuum Energy}, author={Scott D. Thomas}, journal={arXiv: High Energy Physics - Theory}, year={2000} }

Gravitational holography is argued to render the cosmological constant stable against divergent quantum corrections. This provides a technically natural solution to the cosmological constant problem. Evidence for quantum stability of the cosmological constant is illustrated in a number of examples including, bulk descriptions in terms of delocalized degrees of freedom, boundary screen descriptions on stretched horizons, and non-supersymmetric conformal field theories as dual descriptions of… Expand

The Cosmological Constant Problem, an Inspiration for New Physics

- Physics
- 2006

We have critically compared different approaches to the cosmological constant problem, which is at the edge of elementary particle physics and cosmology. This problem is deeply connected with the… Expand

Positive vacuum energy and the N-bound

- Physics
- 2000

We argue that the total observable entropy is bounded by the inverse of the cosmological constant. This holds for all space-times with a positive cosmological constant, including cosmologies… Expand

Entropy-area relations in field theory

- Physics
- 2002

We consider the contribution to the entropy from fields in the background of a curved time-independent metric. To account for the curvature of space, we postulate a position-dependent UV cutoff. We… Expand

Holographic dark energy model with non-minimal coupling

- Physics
- 2005

We find that a holographic-dark-energy model with non-minimally coupled scalar field gives rise to an accelerating universe by choosing the Hubble scale as IR cutoff. We show a viable range of the… Expand

Why have we Never Observed the Massless Charged Particle?

- Physics

In this paper we try to explore the possible contact between quantum gravity and the least mass of a charged particle in de Sitter spacetime. The effect of Generalized Uncertainty Principle (GUP) on… Expand

A not so brief commentary on cosmological entropy bounds

- Physics
- 2005

There has been, quite recently, a discussion on how holographic-inspired bounds might be used to encompass the present-day dark energy and early-universe inflation into a single paradigm. In the… Expand

Cosmological Constant from the Emergent Gravity Perspective

Observations indicate that our universe is characterized by a late-time accelerating phase, possibly driven by a cosmological constant $\Lambda$, with the dimensionless parameter $\Lambda L_P^2… Expand
