Evolution of Oscillating Scalar Fields as Dark Energy
Sourish Dutta, Robert J. Scherrer
Oscillating scalar fields, with an oscillation frequency much greater than the expansion rate, have been proposed as models for dark energy. We examine these models, with particula…

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…

Voids of dark energy
Sourish Dutta, Irit Maor
We investigate the clustering properties of a dynamical dark energy component. In a cosmic mix of a pressureless fluid and a light scalar field, we follow the linear evolution of s…
