On Primordial Magnetic Fields
- K. Enqvist
- Physics
- 18 May 1994
A primordial magnetic field could be responsible for the observed magnetic fields of the galaxies. One possibility is that such a primordial field is generated at the electroweak phase transition…
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…
The effect of inhomogeneous expansion on the supernova observations
- K. Enqvist, Teppo Mattsson
- Physics
- 5 September 2006
We consider an inhomogeneous but spherically symmetric Lemaitre–Tolman–Bondi model to demonstrate that spatial variations of the expansion rate can have a significant effect on the cosmological…
MSSM flat direction inflation: slow roll, stability, fine-tuning and reheating
- R. Allahverdi, K. Enqvist, J. García-Bellido, A. Jokinen, A. Mazumdar
- Physics
- 11 October 2006
We consider low scale slow roll inflation driven by the gauge-invariant flat directions udd and LLe of the minimally supersymmetric standard model at the vicinity of a saddle point of the scalar…
Gauge invariant MSSM inflaton
- R. Allahverdi, J. García-Bellido, K. Enqvist, A. Mazumdar
- Physics
- 3 May 2006
We argue that all the necessary ingredients for successful inflation are present in the flat directions of the Minimally Supersymmetric Standard Model. We show that out of many gauge invariant…
Expression of Interest for a very long baseline neutrino oscillation experiment (LBNO)
- A. Stahl, R. P. Litchfield, A. Ariga
- Physics
- 24 June 2012
This Expression of Interest (EoI) describes the motivation for and the feasibility studies of a long baseline neutrino oscillation experiment (LBNO) with a new conventional neutrino beamline facility…

Non-Gaussian perturbations in hybrid inflation
- K. Enqvist, A. Vaihkonen
- Economics
- 12 May 2004
We consider second-order inflationary perturbations in the case of two scalar fields, σ and the inflaton . We derive an expression for the non-Gaussianity of perturbations and apply the results to…
