A field theory approach to cosmological density perturbations
Zdzislaw A. Golda, Andrzej Woszczyna
TL;DR
This paper presents a novel approach to cosmological density perturbations by modeling their propagation as scalar massless fields within an effective Robertson-Walker space-time, offering new insights into early universe fluctuations.
Contribution
Introduces a field theory framework for analyzing adiabatic perturbations in the expanding universe, connecting cosmological perturbations with scalar field dynamics.
Findings
Perturbations behave like scalar massless fields in an effective space-time.
Provides a new perspective on the evolution of density fluctuations.
Lays groundwork for further theoretical exploration of cosmological perturbations.
Abstract
Adiabatic perturbations propagate in the expanding universe like scalar massless fields in some effective Robertson-Walker space-time.
