Constraining extra dimensions using observations of black hole quasi-normal modes. [PDF]

open access: yesEur Phys J C Part Fields, 2022
The presence of extra dimensions generically modify the spacetime geometry of a rotating black hole, by adding an additional hair, besides the mass M and the angular momentum J, known as the ‘tidal charge’ parameter, β\documentclass[12pt]{minimal ...

Growing extra dimensions in AdS/CFT [PDF]

open access: yesJournal of High Energy Physics, 2019
What is the dimension of spacetime? We address this question in the context of the AdS/CFT Correspondence. We give a prescription for computing the number of large bulk dimensions, D, from strongly-coupled CFT d data, where “large” means parametrically ...

Extra kinetic dimensions for label discrimination

open access: yesNature Communications, 2022
Label discrimination is challenging in fluorescence microscopy due to broad spectra and narrow lifetime distribution. Here, the authors introduce extra kinetic dimensions by illuminating reversibly photoswitchable fluorophores with different intensities,

Dark energy, extra dimensions, and the Swampland [PDF]

open access: yesJournal of High Energy Physics, 2020
Perhaps the greatest challenge for fundamental theories based on compactification from extra dimensions is accommodating a period of accelerated cosmological expansion.

Gravity and Large Extra Dimensions [PDF]

open access: yesAdvances in Astronomy, 2011
The idea that quantum gravity can be realized at the TeV scale is extremely attractive to theorists and experimentalists alike. This proposal leads to extra spacial dimensions large compared to the Planck scale.

Search for dark matter, extra dimensions, and unparticles in monojet events in proton-proton collisions at [Formula: see text][Formula: see text]. [PDF]

open access: yesEur Phys J C Part Fields, 2015
Results are presented from a search for particle dark matter (DM), extra dimensions, and unparticles using events containing a jet and an imbalance in transverse momentum. The data were collected by the CMS detector in proton–proton collisions at the LHC

Lorentz Violation in Extra Dimensions [PDF]

open access: green, 2005
In theories with extra dimensions it is well known that the Lorentz invariance of the $D=4+n$-dimensional spacetime is lost due to the compactified nature of the $n$ dimensions leaving invariance only in 4d.

Non-invertible flavor symmetries in magnetized extra dimensions [PDF]

open access: yesJournal of High Energy Physics
We discuss non-invertible symmetries in toroidal compactifications of higher dimensional Yang-Mills theory with magnetic fluxes, which can be regarded as an effective action of type IIB string theory with magnetized D-branes.

Exploring extra dimensions through inflationary tensor modes [PDF]

open access: yesJournal of High Energy Physics, 2018
Predictions of inflationary schemes can be influenced by the presence of extra dimensions. This could be of particular relevance for the spectrum of gravitational waves in models where the extra dimensions provide a brane-world solution to the hierarchy ...

Strong gravitational lensing—a probe for extra dimensions and Kalb-Ramond field [PDF]

open access: green, 2017
Strong field gravitational lensing in the context of both higher spacetime dimensions and in presence of Kalb-Ramond field have been studied. After developing proper analytical tools to analyze the problem we consider gravitational lensing in three ...
