14. Inferring properties of dark energy from the large scale structure of the universe

Anthony Scott Carr (KASI)

The structure of galaxies we see in the sky today was seeded in the very early universe. The evolution from initial tiny density perturbations to the cosmic web of voids, clusters and filaments of galaxies tells us about what the universe is made of. There are many ways to utilise this large scale structure to probe cosmology, but measuring the growth rate itself in the nearby universe is...

15. Holographic Entanglement Entropy in the FLRW Universe

Fumiya Sano (IBS CTPU-CGA)

We compute a holographic entanglement entropy via Ryu-Takayanagi prescription in the three-dimensional Friedmann-Lemaître-Robertson-Walker universe. We consider two types of holographic scenarios analogous to the static patch holography and the half de Sitter holography, in which the holographic boundary is timelike and placed in the bulk. We find in general that the strong subadditivity can...

24. Decay and lifetime of oscillons coupled to an external scalar field: Insights from instability band analysis

Siyao Li (IBS CTPU-CGA)

7/31/25, 3:05 PM

Oscillons are long-lived, spherically symmetric solitons that can arise in real scalar field theories with potentials shallower than quadratic ones. They are considered to form via parametric resonance during the preheating stage after inflation and have extended lifetimes. However, the estimation of their lifespan becomes complicated when taking into account the interactions between the...
