Constraints on Stable Scalar-Tensor Dark Energy from DESI Data and Solar System Tests
Husam Adam, Mark P. Hertzberg, Daniel Jiménez-Aguilar
We investigate the viability of scalar-tensor (quintessence) models of dark energy with a quartic polynomial nonminimal coupling to gravity and a linear scalar potential. The polyn…
Cuspidal Singularities in Collapsing Domain Walls
Jose J. Blanco-Pillado, Matthew Elley, Francesc Ferrer +4
Domain wall networks have attracted renewed interest, particularly in relation to the dynamics of network collapse. Accurately describing this process is challenging and typically…
Accelerated expansion of the universe purely driven by scalar field fluctuations
Daniel Jiménez-Aguilar
We show that scalar field fluctuations alone can drive cosmic acceleration, provided the universe is spatially closed and the Compton wavelength of the field exceeds the radius of…
