Perturbations in generalized multi-field inflation
We study the linear perturbations of multi-field inflationary models governed by a Lagrangian which is a general function of the scalar fields and of a global kinetic term combining their spacetime gradients with an arbitrary field space metric. Our analysis includes k -inflation, Dirac-Born-Infeld inflation and its multi-field extensions which have been recently studied. For this general class...
متن کاملGeneration of perturbation after multi - field inflation
We explore a new possibility that some inflaton fields in multi-field inflation models satisfy the observed value of the spectral index so that the curvature perturbation generated by them through post-inflationary dynamics may be relevant for the current observations. We illustrate this point using a simple and reasonable multi-field chaotic inflation model motivated from string theory. Possib...
متن کاملMulti-field Inflation with a Random Potential
Motivated by the possibility of inflation in the cosmic landscape, which may be approximated by a complicated potential, we study the density perturbations in multi-field inflation with a random potential. The random potential causes the inflaton to undergo a Brownian motion with a drift in the D-dimensional field space, allowing the entropic perturbation modes to continuously and randomly feed...
متن کاملDynamics of Multi-Component, Multi-Field Quintessence
Self-consistent dynamics of the multi-component, N -field quintessence and gravity is formulated as relativistic N -body dynamics, embedded in a static viscous flat space and under the forces given by the interacting Lorentz scalar potential via exchanges of field bosons. The Ratra-Peebles power-law potential of effective single-field quintessence can be derived from this ”microscopic” perspect...
متن کاملSustainability of multi-field inflation and bound on string scale
We study the effects of the interaction terms between the inflaton fields on the inflationary dynamics in multi-field models. With power law type potential and interactions, the total number of e-folds may get considerably reduced and can lead to unacceptably short period of inflation. Also we point out that this can place a bound on the characteristic scale of the underlying theory such as str...
