Supersymmetric relics from the big bang

- J. Ellis, J. Hagelin, D. Nanopoulos, K. Olive, M. Srednicki
- Physics
- 11 June 1984

Abstract We consider the cosmological constraints on supersymmetric theories with a new, stable particle. Circumstantial evidence points to a neutral gauge/Higgs fermion as the best candidate for… Expand

Tests of quantum gravity from observations of γ-ray bursts

- G. Amelino-Camelia, J. Ellis, N. Mavromatos, D. Nanopoulos, S. Sarkar
- Physics
- Nature
- 25 June 1998

The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. Here… Expand

Mutations in the neuronal-specific microtubule-binding protein TAU are associated with several dementias and neurodegenerative diseases. However, the effects of elevated TAU accumulation on… Expand

Quantum-gravity analysis of gamma-ray bursts using wavelets

- J. Ellis, N. Mavromatos, D. Nanopoulos, A. Sakharov
- Physics
- 4 October 2002

In some models of quantum gravity, space-time is thought to have a foamy structure with non-trivial optical prop- erties. We probe the possibility that photons propagating in vacuum may exhibit a… Expand

Tubulin dipole moment, dielectric constant and quantum behavior: computer simulations, experimental results and suggestions.

- Physics, Medicine
- Bio Systems
- 10 February 2004

We used computer simulation to calculate the electric dipole moments of the alpha- and beta-tubulin monomers and dimer and found those to be |p(alpha)| = 552D, |p(beta)| = 1193D and |p(alphabeta)| =… Expand

OBSERVABLES IN LOW-ENERGY SUPERSTRING MODELS

- J. Ellis, K. Enqvist, D. Nanopoulos, F. Zwirner
- Physics
- 1986

We compile phenomenological constraints on the minimal low-energy effective theory which can be obtained from the superstring by Calabi-Yau compactification. Mixing with the single additional neutral… Expand

Naturally Vanishing Cosmological Constant in N=1 Supergravity

- E. Cremmer, S. Ferrara, C. Kounnas, D. Nanopoulos
- Physics
- 8 December 1983

Abstract For N =1 supergravity theories we show that the choice of a particular class of Einstein spaces for the Kahler manifold of the hidden sector leads to a vanishing cosmological constant… Expand

Robust Limits on Lorentz Violation from Gamma-Ray Bursts

- J. Ellis, N. Mavromatos, +6 authors E. Sarkisyan
- Physics
- 1 July 2006

Abstract We constrain the possibility of a non-trivial refractive index in free space corresponding to an energy-dependent velocity of light: c ( E ) ≃ c 0 (1 − E / M ), where M is a mass scale… Expand

Starobinsky-like inflationary models as avatars of no-scale supergravity

- J. Ellis, D. Nanopoulos, K. Olive
- Physics
- 12 July 2013

Models of cosmological inflation resembling the Starobinsky R+R2 model emerge naturally among the effective potentials derived from no-scale SU(N,1)/SU(N) × U(1) supergravity when N > 1. We display… Expand
