Spatial Phonons: A Phenomenological Viscous Dark Energy Model for DESI
Muhammad Ghulam Khuwajah Khan
We explore a phenomenological model of dark energy in which space is treated as an elastic brane with uniform tension and supports a longitudinal phonon sector described by t…

The tension of space as dark energy: dynamics and phenomenology
Muhammad Ghulam Khuwajah Khan
We develop a phenomenological model in which the observed late-time dark-energy sector is interpreted as an effective residual tension of space. Motivated by recent observational h…
