Eternal inflation and the quantum birth of cosmic structure

Understand

We consider the eternal inflation scenario of the slow-roll/chaotic type with the additional element of an objective collapse of the wave function.

• The incorporation of this new agent to the traditional inflationary setting might represent a possible solution to the quantum measurement problem during inflation, a subject that has not reached a consensus among the community.
• Specifically, it could provide an explanation for the generation of the primordial anisotropies and inhomogeneities, starting from a perfectly symmetric background and invoking symmetric dynamics.
• We adopt the continuous spontaneous localization model, in the context of inflation, as the dynamical reduction mechanism that generates the primordial inhomogeneities.
