We use experimental limits on Lorentz violation to obtain new constraints on Kaluza-Klein-type theories in which the extra dimensions may be large but do not necessarily have units of length. The associated variation in fundamental quantities such as rest mass must occur slowly, on cosmological scales.

Constraints on Space-Time-Matter Theory in the Framework of the Standard-Model Extension

We use experimental limits on Lorentz violation within the framework of the Standard-Model Extension to derive quantitative constraints on Space-Time-Matter theory, a version of Kaluza–Klein theory…

Optimal estimation of parameters for scalar fields in expanding universe exhibiting Lorentz invariance violation.

We address the optimal estimation of quantum parameters, in the framework of local quantum estimation theory, for a massive scalar quantum field in the expanding Robertson-Walker universe exhibiting…

Induced equation of state for the universe epochs constrained by the hubble parameter

Optimal estimation of parameters for scalar field in an expanding spacetime exhibiting Lorentz invariance violation

It is proved that the appropriate momentum mode of field particles and larger cosmological parameters can provide us a better precision in the estimation of LIV parameter during the spacetime expansion.

Physics and the Pythagorean Theorem

Pythagoras' theorem lies at the heart of physics as well as mathematics, yet its historical origins are obscure. We highlight a purely pictorial, gestalt-like proof that may have originated during…
