چکیده

Damour and Mukhanov have recently devised circumstances in which in ation may continue during the oscillatory phase which ensues once the in aton eld reaches the minimum of its potential. We con rm the existence of this phenomenon by numerical integration. In such circumstances the quanti cation of the amount of in ation requires particular care. We use a de nition based on the decrease of the comoving Hubble length, and show that Damour and Mukhanov overestimated the amount of in ation occurring. We use the numerical calculations to check the validity of analytic approximations.

Pair Creation of Dilaton Black Holes in Extended In ation

Dilatonic Charged Nariai instantons mediate the nucleation of black hole pairs during extended chaotic in ation. Depending on the dilaton and in aton elds, the black holes are described by one of two approximations in the Lorentzian regime. For each case we nd Euclidean solutions that satisfy the no boundary proposal. The complex initial values of the dilaton and in aton are determined, and the...

False Vacuum In ation with Einstein Gravity

We present a detailed investigation of chaotic in ation models which feature two scalar elds, such that one eld (the in aton) rolls while the other is trapped in a false vacuum state. The false vacuum becomes unstable when the magnitude of the in aton eld falls below some critical value, and a rst or second order transition to the true vacuum ensues. Particular attention is paid to the case, te...

Some aspects of thermal in ation : the nite temperature potential and topological defects

Currently favoured extensions of the Standard Model typically contain ` aton elds' de ned as elds with large vacuum expectation values (vevs) and almost at potentials. If a aton eld is trapped at the origin in the early universe, one expects `thermal in ation' to take place before it rolls away to the true vacuum, because the nite-temperature correction to the potential will hold it at the orig...

Relating spectral indices to tensor and scalar amplitudes in inflation.

Within an expansion in slow-roll in ation parameters, we derive secondorder expressions relating the ratio of tensor to scalar density perturbations and the spectral index of the scalar spectrum. We nd that \corrections" to previously derived formulae can dominate if the tensor to scalar ratio is small. For instance, if V V 00=(V ) 6= 1 or if mP l=(4 ) jV 000=V j > 1, where V ( ) is the in aton...

UM-AC-95-11 hep-ph/9512211 MODULI INFLATION WITH LARGE SCALE STRUCTURE PRODUCED BY TOPOLOGICAL DEFECTS

It is tempting to in ate along one of the many at directions that arise in supersymmetric theories. The required atness of the potential to obtain su cient in ation and to not overproduce density uctuations occurs naturally. However, the density perturbations (in the case of a single moduli eld) that arise from in aton quantum uctuations are too small for structure formation. Here we propose th...
