Glimpses of extra dimension models
In this short review, we discuss the salient features of the model and phenomenology of Large, Warped and Universal extra dimensional models. Models...

On aether terms in a space-time with a compact extra dimension
In this paper, we explicitly calculate the aether-like corrections for the electromagnetic field in the case when the space-time involves an extra...

Compactified extra dimension and entanglement island as clues to quantum gravity
We show that the compactified extra dimension and the emergence of the island can provide clues about quantum gravity because their combination can...

Lightcone fluctuations in a five dimensional Kaluza-Klein model and an estimation on the size of the extra dimension
In this work we consider lightcone fluctuation effects in a five-dimensional spacetime arising as a consequence of the compactification of the extra...

QCD Inspired Potential in a Space with One Extra-Dimension and Masses of Heavy Flavour Mesons
Motivated by the recent developments in stability of hydrogen atom in a space with one finite extra-dimension,we consider that physical mesons are...

Gravity-matter sum rules in models with a single extra-dimension
We prove a set of sum rules needed for KK-graviton pair production from matter in orbifolded extra-dimensional models. The sum rules can be found in...

Multiple hierarchies from a warped extra dimension
Theories beyond the Standard Model often contain mass scales hierarchically different from the electroweak scale and the Planck scale. It has been...

Wormholes with a warped extra dimension?
We investigate the role of a specifically warped extra dimension in constructing examples of higher dimensional spacetimes representing Lorentzian...

Quantum gravity induced entanglement of masses with extra dimensions
It is believed that gravity can be considered as a quantum coherent mediator. In this study, we propose a plan to test the existence of extra...

Extra dimensions with light and heavy neutral leptons: an application to CEνNS
We explore the possibility of relating extra dimensions with light and heavy Dirac-type neutral leptons and develop a framework for testing them in...

Fate of domain walls in 5D gravitational theory with compact extra dimension
We pursue the time evolution of the domain walls in 5D gravitational theory with a compact extra dimension by numerical calculation. In order to...

The Scale of Supersymmetry Breaking and the Dark Dimension
We argue for a relation between the supersymmetry breaking scale and the measured value of the dark energy density Λ. We derive it by combining two...

Dark dimension gravitons as dark matter
We consider cosmological aspects of the Dark Dimension (a mesoscopic dimension of micron scale), which has recently been proposed as the unique...

Single extra dimension from κ-Poincaré and gauge invariance
We show that κ -Poincaré invariant gauge theories on κ -Minkowski space with physically acceptable commutative (low energy) limit must be 5-d. The...

Extra Dimensions and Physics of Low-Scale Strings
This review aims to provide a very short and pedestrian introduction to some of the basics of extra-dimensional physics. The hope is to facilitate...

The dark dimension and the Swampland
Motivated by principles from the Swampland program, which characterize requirements for a consistent UV completion of quantum gravity, combined with...

Superluminal propagation along the brane in space with extra dimensions
We demonstrate that a model with extra dimensions formulated in Csaki et al. (Phys Rev D 62:045015, 2000), which fatefully reproduces...

Tera-sample-per-second arbitrary waveform generation in a synthetic dimension
Synthetic dimension opens new horizons in quantum physics and topological photonics by enabling new dimensions for field and particle manipulations....

Constraining extra dimensions using observations of black hole quasi-normal modes
The presence of extra dimensions generically modify the spacetime geometry of a rotating black hole, by adding an additional hair, besides the mass M ...

Cap** the positivity cone: dimension-8 Higgs operators in the SMEFT
SMEFT Wilson coefficients are subject to various positivity bounds in order to be consistent with the fundamental principles of S-matrix. Previous...
