From configuration to dynamics -- Emergence of Lorentz signature in classical field theory
Shinji Mukohyama, Jean-Philippe Uzan
The Lorentzian metric structure used in any field theory allows one to implement the relativistic notion of causality and to define a notion of time dimension. This article investi…
Radiative corrections to scalar masses in de Sitter space
T. Brunier, F. Bernardeau, J. -P. Uzan
We compute the radiative corrections to the mass of a test boson field in an inflating space-time. The calculations are carried out in case of a boson part of a supersymmetric chir…
Stability of six-dimensional hyperstring braneworlds
Christophe Ringeval, Patrick Peter, Jean-Philippe Uzan
We study a six-dimensional braneworld model with infinite warped extra dimensions in the case where the four-dimensional brane is described by a topological vortex of a U(1) symmet…
Trans-Planckian Dark Energy?
Martin Lemoine, Jerome Martin, Jean-Philippe Uzan
It has recently been proposed by Mersini et al. 01, Bastero-Gil and Mersini 02 that the dark energy could be attributed to the cosmological properties of a scalar field with a non-…
