The accelerating expansion of the Universe points to a small positive value for the cosmological constant or vacuum energy density. We discuss recent ideas that the cosmological constant plus LHC results might hint at critical phenomena near the Planck scale. 
Cosmological constant problem: deflation during inflation
We argue that the discrepancy between the Planck mass scale and the observed value of the cosmological constant can be largely attenuated, if those quantities are understood as a result of effective,
Fundamental Constants in Physics and Their Time Variation
There is no doubt that the field of Fundamental Constants in Physics and Their Time Variation is one of the hottest subjects in modern theoretical and experimental physics, with potential
Dark Energy, Dark Matter and the Accelerating Expansion of Space
The dark energy density has been derived from the density of vacuum energy at the scale of the Bohr radius in a ten-dimensional model, and from the radius of the observable universe. The Bohr radius
Vacuum energy in some particular quantum field theories
We study the properties of a class of quantum field theories endowed with an equal number of anti commuting and commuting field variables, the most common example being the supersymmetric models.
Fundamental constants and cosmic vacuum: the micro and macro connection
The idea that the vacuum energy density $\rho_{\Lambda}$ could be time dependent is a most reasonable one in the expanding Universe; in fact, much more reasonable than just a rigid cosmological
Thermodynamics of Modified Cosmic Chaplygin Gas
We examine the thermodynamic features of an exotic fluid known as modified cosmic Chaplygin gas in the context of homogeneous isotropic universe model. For this purpose, the behavior of physical
Dynamical systems analysis of the cubic galileon beyond the exponential potential and the cosmological analogue of the vDVZ discontinuity
In this paper we generalize the dynamical systems analysis of the cubic galileon model previously investigated in De Arcia et al (2016 Class. Quantum Grav. 33 125036) by including self-interaction
Free Scalar Fields in Finite Volume Are Holographic
This brief note presents a back-of-the-envelope calculation showing that the number of degrees of freedom of a free scalar field in expanding flat space equals the surface area of the Hubble volume


The Cosmological Constant
A pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the physics of a small (and potentially nonzero) vacuum energy are presented.
The cosmological constant puzzle
The accelerating expansion of the Universe points to a small positive vacuum energy density and negative vacuum pressure. A strong candidate is the cosmological constant in Einstein's equations of
The Cosmological Constant Problem
Astronomical observations indicate that the cosmological constant is many orders of magnitude smaller than estimated in modern theories of elementary particles. After a brief review of the history of
The Cosmological Constant Puzzle: Vacuum Energies from QCD to Dark Energy
The accelerating expansion of the Universe points to a small positive vacuum energy density and negative vacuum pressure. A strong candidate is the cosmological constant in Einstein’s equations of
Running of the Cosmological Constant and Estimate of its Value in Quantum General Relativity
We present the connection between the running of the cosmological constant and the estimate of its value in the resummed quantum gravity realization of quantum general relativity. We also address in
The Cosmological Constant Puzzle: Synergies with Nuclear Physics and its Measurement in Astrophysics Experiments
Accelerating expansion of the Universe was discovered in the observations of distant Supernovae 1a, and recognized by the 2011 physics Nobel Prize. How to understand this acceleration brings together
Emergent Photons and Gravitons:The Problem of Vacuum Structure
We discuss vacuum condensates associated with emergent QED and with torsion, as well as the possible role of the Kodama wave function in quantum cosmology.
Cosmological Evolution of Fundamental Constants: From Theory to Experiment
In this paper we discuss a possible cosmological time evolution of fundamental constants from the theoretical and experimental point of views. On the theoretical side, we explain that such a
Emergence of a 4D world from causal quantum gravity.
Evidence is presented that a macroscopic four-dimensional world emerges from Causal Dynamical Triangulations in four dimensions dynamically, which provides a background-independent definition of the sum over geometries in nonperturbative quantum gravity.
