El próximo miércoles 27 de mayo, el Dr. Gonzalo Palma, cosmólogo teórico y académico de la Universidad de Chile, dictará el coloquio “From the Wavefunction of the Universe to In-In-Correlators: A Perturbative Map to All Orders” a las 11 horas en la Sala 208 del Instituto de Física, Edificio de Ciencias, Campus Curauma, PUCV.
Compartimos el resumen de la presentación:
In this talk, I will review recent progress in the systematic computation of primordial correlation functions. These quantities are central theoretical tools for connecting models of the early universe with cosmological observations. Two complementary frameworks play a key role in this problem: the Wavefunction of the Universe approach and the Schwinger-Keldysh, or in-in, formalism. Both are designed to describe the same physical observables, but they organize computations in rather different ways. Although their conceptual equivalence has long been appreciated, the precise relation between their diagrammatic expansions has remained somewhat obscure. I will describe a recent construction that makes this relation explicit. The result provides a clearer understanding of how different perturbative approaches to primordial cosmology are connected, and offers a useful perspective on the structure of cosmological observables.
Extendemos la invitación a la comunidad del Instituto de Física y público interesado a participar de este coloquio.
