Nflation: observable predictions from the random matrix mass spectrum
Soo A Kim, Andrew R Liddle
We carry out numerical investigations of the perturbations in Nflation models where the mass spectrum is generated by random matrix theory. The tensor-to-scalar ratio and non-gauss…
Nflation: non-gaussianity in the horizon-crossing approximation
Soo A. Kim, Andrew R. Liddle
We analyze the cosmic non-gaussianity produced in inflation models with multiple uncoupled fields with monomial potentials, such as Nflation. Using the horizon-crossing approximati…
Nflation: multi-field inflationary dynamics and perturbations
Soo A Kim, Andrew R Liddle
We carry out numerical investigations of the dynamics and perturbations in the Nflation model of Dimopoulos et al. (2005). This model features large numbers of scalar fields with d…
Dynamics of assisted quintessence
Soo A Kim, Andrew R Liddle, Shinji Tsujikawa
We explore the dynamics of assisted quintessence, where more than one scalar field is present with the same potential. For potentials with tracking solutions, the fields naturally…
