Quasibound and quasinormal modes of a thick brane in Rastall gravity

Journal of High Energy Physics
In this work, we study the gravitational quasinormal modes of the thick brane in Rastall gravity. Using the asymptotic iteration and direct integration methods, we solve the quasinormal frequencies of the Rastall thick brane.

Detecting extra dimensions by Hydrogen-like atoms

Open Physics, 2015
We reconsider the idea in spectroscopy of detecting extra dimensions by regarding the nucleus as a homogeneous sphere. In our results, it turns out that the gravitational potential inside the nucleus is much stronger than the potential induced by a ...

Fundamental Units of Measurement and Extra Dimensions

Advances in High Energy Physics, 2022
The space available to our perception is three-dimensional with full evidence. The development of physics led to the hypothesis of extra dimensions. It is believed that an important role in the unification of physics should play by the Planck units of ...

Large extra dimensions at the Deep Underground Neutrino Experiment [PDF]

, 2016
We investigate the potential of the long-baseline Deep Underground Neutrino Experiment (DUNE) to study large-extra-dimension (LED) models originally proposed to explain the smallness of neutrino masses by postulating that right-handed neutrinos, unlike ...

Quasinormal modes and echoes of a double braneworld

Journal of High Energy Physics
In this work, we study the gravitational quasinormal modes and the gravitational echoes of a double braneworld. The double braneworld is a kind of split thick brane, which is crucial for addressing the hierarchy problem in the thick brane scenarios ...

Bispectrum from five-dimensional inflation

Journal of High Energy Physics
It was proposed that five-dimensional (5D) inflation can blow up the size of a compact dimension from the 5D Planck length to the micron size, as required by the dark dimension proposal, relating the weakness of the actual gravitational force to the size

Localization of scalar field on the brane-world by coupling with gravity

Journal of High Energy Physics
In this paper, we consider a coupling mechanism between the kinetic term and the gravity, in which a coupling function F (R) is introduced into the kinetic term of the five-dimensional scalar field. Based on this scenario, we investigate the localization

Quasinormal ringing of de Sitter braneworlds

Journal of High Energy Physics
Compared with the Poincaré braneworld, the de Sitter (dS) braneworld aligns more closely with the present universe characterized by a small but finite cosmological constant.

Flavour physics and extra-dimensions

EPJ Web of Conferences, 2018
Randall-Sundrum (RS) model of warped extra-dimensions were originally proposed to explain the Planck-weak scale hierarchy. It was soon realised that modifications of the original setup, by introducing the fields in the bulk, has several interesting ...

Constraints on extra dimensions from precision molecular spectroscopy [PDF]

, 2015
Accurate investigations of quantum-level energies in molecular systems are shown to provide a testing ground to constrain the size of compactified extra dimensions.
