UniverseThe origin and evolution of supermassive black holes (SMBHs) in our universe have sparked controversy. In this study, we explore the hypothesis that some of these black holes may have seeded from the direct collapse of dark energy domains with density ...

4 + n-dimensional water and waves on four and eleven-dimensional manifolds
Open Physics, 2018 In this paper, we consider the structure of water and waves from viewpoints of two observers, one on 4-dimensional manifold and the other on 11-dimensional manifold.

Inhomogeneous compact extra dimensions and de Sitter cosmology
European Physical Journal C: Particles and Fields, 2020 In the framework of multidimensional f(R) gravity, we study the possible metrics of compact extra dimensions assuming that our 4D space has the de Sitter metric.

A Large mass hierarchy from a small extra dimension [PDF]
, 1999 We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from the Planck scale through an exponential hierarchy.

Searches for power-law warped extra dimensions
Journal of High Energy PhysicsExtra dimensions with a bulk dilaton field can be power-law warped, unlike the exponential warping in the Randall-Sundrum (RS) model. We show that this mildly warped extra dimension can address the hierarchy problem with a novel Kaluza-Klein (KK ...

Swampland bounds on magnetized extra dimensions
Journal of High Energy PhysicsWe consider a six-dimensional U(1) gauge theory compactified on two-dimensional manifolds. The number of chiral fermions is determined by the flux quantization number on the two-dimensional compact manifolds.

Extra dimensions hypothesis in high energy physics
EPJ Web of Conferences, 2017 We discuss the history of the extra dimensions hypothesis and the physics and phenomenology of models with large extra dimensions with an emphasis on the Randall- Sundrum (RS) model with two branes. We argue that the Standard Model extension based on the
