Electroweak preheating on a lattice
A. Rajantie, P. M. Saffin, E. J. Copeland
In many inflationary models, a large amount of energy is transferred rapidly to the long-wavelength matter fields during a period of preheating after inflation. We study how this c…
On non-perturbative corrections to the Kahler potential
T. Barreiro, B. de Carlos, E. J. Copeland
We present the results of a detailed investigation into the consequences of adding specific string motivated non-perturbative corrections to the usual tree level Kahler potential i…
Electrically Charged Sphalerons
P. M. Saffin, E. J. Copeland
We investigate the possibility that the Higgs sector of the Weinberg-Salam model admits the existence of electrically charged, sphaleron states. Evidence is provided through an asy…
Some aspects of thermal inflation: the finite temperature potential and topological defects
Tiago Barreiro, E. J. Copeland, David H. Lyth +1
Currently favoured extensions of the Standard Model typically contain `flaton fields' defined as fields with large vacuum expectation values (vevs) and almost flat potentials. If a…
Reconstructing the Inflaton Potential---in Principle and in Practice
Edmund Copeland, Edward W. Kolb, Andrew R. Liddle +1
Generalizing the original work by Hodges and Blumenthal, we outline a formalism which allows one, in principle, to reconstruct the potential of the inflaton field from knowledge of…
