Preheating with Non-Minimal Kinetic Terms
Hillary L. Child, John T. Giblin, Raquel H. Ribeiro +1
We present the first 3+1-dimensional numerical simulations of scalar fields with non-minimal kinetic terms. As an example, we examine the existence and stability of preheating in t…
General CMB bispectrum analysis using wavelets and separable modes
Donough Regan, Pia Mukherjee, David Seery
In this paper we combine partial-wave (`modal') methods with a wavelet analysis of the CMB bispectrum. Our implementation exploits the advantages of both approaches to produce robu…
Scale-dependent bias from multiple-field inflation
Mafalda Dias, Raquel H. Ribeiro, David Seery
We provide a formula for the scaling behaviour of the inflationary bispectrum in the 'squeezed' limit where one momentum becomes much smaller than the other two. This determines th…
