Our universe seems to be radiation dominated at early times, and vacuum energy dominated at late times. When we consider the maximal analytic extension of this spacetime, its symmetries and complex analytic properties suggest a picture in which spacetime has two sheets, exchanged by an isometry which, in turn, picks a preferred (CPT-symmetric) vacuum state for quantum fields on the spacetime. Previously [1, 2], we showed how this line of thought provides new explanations for dark matter, the… Expand

Cancelling the vacuum energy and Weyl anomaly in the standard model with dimension-zero scalar fields
• Physics
• 2021
The standard model is a remarkably consistent and complete quantum field theory but its coupling to gravity and the Higgs field remain problematic, as reflected in the cosmological constant problem,Expand
Big bang as topological quantum phase transition
• Physics
• 2021
It has been argued that a special quantum-vacuum variable q can provide a solution to the main cosmological constant problem and possibly also give a cold-dark-matter component. We now show that theExpand

CPT-Symmetric Universe.
• Physics, Medicine
• Physical review letters
• 2018
The Universe after the big bang is the CPT image of the Universe before it, both classically and quantum mechanically, providing a new interpretation of the cosmological baryon asymmetry, as well as a remarkably economical explanation for thecosmological dark matter. Expand
The Big Bang, CPT, and neutrino dark matter
• Physics
• 2018
We investigate the idea that the universe before the Big Bang is the CPT reflection of the universe after the bang, so that the state of the universe does {\it not} spontaneously violate CPT. TheExpand
Stability in Gauged Extended Supergravity
• Physics
• 1982
Extended supergravity theories with gauged SO(N) internal symmetry have, for N ≥ 4, scalar field potentials which are unbounded below. Nevertheless, it is argued that the theories have ground statesExpand

The boundary conditions for gauged supergravity
Abstract Anti-de Sitter space is the natural ground state of the O(N) gauged supergravity theories. If the excited states approach anti-de Sitter space sufficiently fast at infinity that one canExpand

This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Our results are inExpand
Quantum field theory in anti-de Sitter space-time
• Physics
• 1978
We consider the problem of quantizing scalar fields propagating in anti--de Sitter space-time. This space-time is static but not globally hyperbolic and hence the usual quantization procedures areExpand
The Road to Reality : A Complete Guide to the Laws of the Universe
For the title of his latest epic, The Road to Reality , Roger Penrose has selected a metaphor that appears frequently in popular expositions of physics. It is no wonder that the phrase has become aExpand
On the new improved energy-momentum tensor
The requirement of the conformal covariance of the theory in the limit of vanishing masses leads to “improving” terms in energy-momentum tensor. Some consequences of the fact are briefly summarized.
