Extra dimensions and inflation [PDF]
Physics Letters B, 1999 It has been proposed that, without invoking supersymmetry, it is possible to solve the hierarchy problem provided the fundamental scale in the higher dimensional theory is at a much lower scale than the Planck scale. In this paper we consider a toy model where we allow $4+d$ dimensions to evolve from a region determined by the new fundamental scale ...

Phenomenology of Extra Dimensions [PDF]
Strings, Branes and Extra Dimensions, 2004 If the structure of spacetime is different than that readily observed, gravitational physics, particle physics and cosmology are all immediately affected. The physics of extra dimensions offers new insights and solutions to fundamental questions arising in these fields. Novel ideas and frameworks are continuously born and evolved.

Extra kinetic dimensions for label discrimination
Nature 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,

Hiding an extra dimension [PDF]
Journal of High Energy Physics, 2006 We propose a new geometry and/or topology of a single extra dimension whose Kaluza-Klein excitations do appear at much higher scale than the inverse of the length/volume. For a single extra dimenion with volume $Nπρ$ which is made of N intervals with size $πρ$ attached at one point, Kaluza-Klein excitations can appear at $1/ρ$ rather than $1/Nρ$ which ...

Domain with Noncompactified Extra Dimensions in the Multidimensional Universe with Compactified Extra Dimensions [PDF]
General Relativity and Gravitation, 1998 It is supposed that in our Universe with compactified extra dimensions (ED) the domains exist with noncompactified ED. Such domain can be a wormhole-like solution in multidimensional gravity (MD), located between two null surfaces. With the availability of compactification mechanism this MD domain can be joined on null surfaces with two black holes ...

Localization of spinor fields in higher-dimensional braneworlds
Journal of High Energy Physics, 2023 In this paper we investigate the localization of spinor fields in braneworld models by reducing a Dirac spinor in 2n + 2-dimensional spacetime to spinors in 2n dimensions.

Growing extra dimensions in AdS/CFT
Journal 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 ...
