TL;DR
This paper introduces a holographic dual model for (pseudo-)conformal cosmology involving a scalar field forming a moving domain wall in AdS_5, with a regular 5D solution that separates vacua of different energies.
Contribution
It presents a novel holographic dual construction for (pseudo-)conformal cosmology with a regular 5D solution, improving upon previous models.
Findings
The 5D solution is regular in the relevant spacetime domain.
The scalar field forms a moving domain wall in AdS_5.
The domain wall separates vacua with unequal energy densities.
Abstract
We propose a holographic dual for (pseudo-)conformal cosmological scenario, with a scalar field that forms a moving domain wall in adS_5. The domain wall separates two vacua with unequal energy densities. Unlike in the existing construction, the 5d solution is regular in the relevant space-time domain.
