An Introduction to Extra Dimensions [PDF]
Journal of Physics: Conference Series, 2005 Models that involve extra dimensions have introduced completely new ways of looking up on old problems in theoretical physics. The aim of the present notes is to provide a brief introduction to the many uses that extra dimensions have found over the last

Large extra dimensions from higher-dimensional inflation [PDF]
Physical Review D, 2023 We propose the possibility that compact extra dimensions can obtain large size by higher dimensional inflation, relating the weakness of the actual gravitational force to the size of the observable universe.

Large extra dimensions and neutrino experiments [PDF]
Physical Review D, 2022 The existence of Large Extra Dimensions can be probed in various neutrino experiments. We analyze several neutrino data sets in a model with a dominant large extra dimension.

Hunting extra dimensions in the shadow of Sgr A* [PDF]
Physical Review D, 2022 We show that the observed angular diameter of the shadow of the ultra compact object Sgr A*, favours the existence of an extra spatial dimension. This holds irrespective of the nature of the ultra compact object, i.e., whether it is a wormhole or, a ...

Looking for extra dimensions in the observed quasi-periodic oscillations of black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Quasi-periodic oscillations, often present in the power density spectrum of accretion disk around black holes, are useful probes for the understanding of gravitational interaction in the near-horizon regime of black holes.

Solar axions in large extra dimensions [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 The axion could be used as a probe for extra dimensions. In large extra dimensions, besides the QCD axion one obtains an infinite tower of massive Kaluza-Klein (KK) states. We describe the processes of KK axions production in the Sun via the axion-photon

Gravitational memory and compact extra dimensions [PDF]
Physical Review D, 2021 We develop a general formalism for treating radiative degrees of freedom near I + in theories with an arbitrary Ricci-flat internal space. These radiative modes are encoded in a generalized news tensor which decomposes into gravitational, electromagnetic,

Gravitational wave from extreme mass-ratio inspirals as a probe of extra dimensions [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 The field of gravitational waves is rapidly progressing due to the noticeable advancements in the sensitivity of gravitational-wave detectors that has enabled the detection prospects of binary black hole mergers. Extreme mass-ratio inspiral (EMRI) is one

Thick brane in Rastall gravity
Journal of High Energy Physics, 2022 In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed. In the flat brane model, the tensor modes of the perturbation are either

Probing compactified extra dimensions with gravitational waves [PDF]
, 2020 We study the effect of compact extra dimensions on the gravitational wave luminosity and waveform. We consider a toy model, with a compactified fifth dimension, and matter confined on a brane.
