Compact, long-range and vacuumless regimes controlled by scalar fields in two-dimensional flat and five-dimensional warped geometries
arXiv:2607.12119 · doi:10.1016/j.aop.2026.170630
summary
The paper analyzes real scalar‑field models in 2D flat space and in a 5D warped AdS background, demonstrating how they can generate compact, long‑range, and vacuumless configurations and the associated brane profiles.
Abstract
We investigate the presence of compact, long-range, and vacuumless regimes in models described by real scalar fields in 2D flat and 5D warped geometries. In the two-dimensional case, we study in detail several models that support localized solutions. When embedded into a warped background, these fields generate distinct kinds of brane profiles.
