Probing String Theory with Modulated Cosmological Fluctuations
Lev Kofman
Superstring theory, models with extra dimensions and other SUSY models generically predict that the coupling constants are in fact vacuum expectation values of fields like the dila…
Gravitational Waves from Braneworld Inflation
Andrei Frolov, Lev Kofman
We investigate the generation of primordial gravitational waves from inflation in braneworld cosmologies with extra dimensions. Advantage of using primordial gravitational waves to…
Tachyonic Preheating
Lev Kofman
I review the theory of preheating after inflation, focusing on the recently found tachyonic preheating in the theories with spontaneous symmetry breaking. This occurs due to the ta…
Preheating, Thermalization and Supergravity
Lev Kofman
This contribution to the proceedings collects new recent results on preheating after inflation. We discuss tachyonic preheating in the SUSY motivated hybrid inflation; development…
Theoretical Tools for Large Scale Structure
J. R. Bond, L. Kofman, D. Pogosyan +1
We review the main theoretical aspects of the structure formation paradigm which impinge upon wide angle surveys: the early universe generation of gravitational metric fluctuations…
Cosmic Web: Origin and Observables
D. Pogosyan, J. R. Bond, L. Kofman +1
Simple analytic arguments are used to understand the predominantly filamentary web in the large-scale distribution of galaxies. Numerical simulations of superclusters are performed…
