Title: From $\lambda\phi^4$ in dS to how inflation starts out of inhomogenous initial conditions

Abstract:

I will first describe how we develop a systematic formalism to compute correlation functions of massless scalar fields in de Sitter space.
Time permitting, I will then show how, using a combination of numerical techniques as well as  techniques from differential geometry, we are shedding light on how inflation starts out of inhomogenous initial conditions.

Biodata of Professor Leonardo Senatore:

Leonardo Senatore began a joint appointment as Assistant Professor in the Department of Physics and the Department of Particle Physics and Astrophysics (PPA) at SLAC, with primary appointment in Physics, in September, 2010. As an undergraduate in Italy, Senatore completed three years of a program in Aerospace Engineering at the Scuola Superiore S. Anna of Pisa, before switching to Physics and receiving his Laurea in Theoretical Physics from the Scuola Normale Superiore of Pisa in 2003. Senatore received his PhD from MIT in April 2006, and then was a postdoctoral researcher jointly at Harvard and the Institute for Advanced Study, Princeton.
