Primordial fluctuations and non-Gaussianities in multi-field DBI inflation
David Langlois, Sebastien Renaux-Petel, Daniele A. Steer +1
We study Dirac-Born-Infeld (DBI) inflation models with multiple scalar fields. We show that the adiabatic and entropy modes propagate with a common effective sound speed and are th…

Creating kinks from particles
Sourish Dutta, D. A. Steer, Tanmay Vachaspati
We study the creation of solitons from particles, using the model as a prototype. We consider the scattering of small, identical, wave pulses, that are equivalent to a seque…

Induced cosmology on a regularized brane in six-dimensional flux compactification
Eleftherios Papantonopoulos, Antonios Papazoglou, Vassilios Zamarias
We consider a six-dimensional Einstein-Maxwell system compactified in an axisymmetric two-dimensional space with one capped regularized conical brane of codimension one. We study t…
