Comparing Minimal and Non-Minimal Quintessence Models to 2025 DESI Data
Husam Adam, Mark P. Hertzberg, Daniel Jiménez-Aguilar +1
In this work we examine the 2025 DESI analysis of dark energy, which suggests that dark energy is evolving in time with an increasing equation of state . We explore a wide range…
From Cusps to Swallowtails: Domain Wall singularities in 2+1 dimensions
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Oriol Pujolàs
The effective Nambu-Goto description of -dimensional domain walls predicts singular behavior of its worldsheet resulting in swallowtail bifurcations. This phenomenon is inti…
Probability of the Initial Conditions for Inflation and Slow Contraction
Mark P. Hertzberg, Daniel Jiménez-Aguilar
Some recent studies based on numerical relativity simulations claim that slow contraction/ekpyrosis is strongly preferred over inflation as the smoothing mechanism that brought the…
