Fine Structure Constant Variation from a Late Phase Transition
Recent experimental data indicates that the fine structure constant α may be varying on cosmological time scales. We consider the possibility that such a variation could be induced by a second order phase transition which occurs at late times (z ∼ 1 3) and involves a change in the vacuum expectation value (vev) of a scalar with milli-eV mass. Such light scalars are natural in supersymmetric the...
متن کاملVariable Fine Structure Constant from Maximal-acceleration Phase Space Relativity
Recently, we presented a new physical model that links the maximum speed of light with the minimal Planck scale into a maximal-acceleration Relativity principle in the spacetime tangent bundle and in phase spaces (cotangent bundle). The maximal proper-acceleration bound is a = c/Λ in full agreement with the old predictions of Caianiello, the Finslerian geometry point of view of Brandt and more ...
متن کاملIndications of a spatial variation of the fine structure constant.
We previously reported Keck telescope observations suggesting a smaller value of the fine structure constant α at high redshift. New Very Large Telescope (VLT) data, probing a different direction in the Universe, shows an inverse evolution; α increases at high redshift. Although the pattern could be due to as yet undetected systematic effects, with the systematics as presently understood the co...
متن کاملOn the cosmological variation of the fine structure constant
A phenomenological model is proposed to explain the recent observed cosmological variation of the fine structure constant as an effect of the quantum vacuum, assuming a flat universe with cosmological constant Λ in the cases (ΩM ,ΩΛ) equal to (0.3, 0.7) and (1, 0). Because of the fourth Heisenberg relation, the lifetime of the virtual pairs of the zero-point radiation must depend on the gravita...
متن کاملSearch for Possible Variation of the Fine Structure Constant
Determination of the fine structure constant α and search for its possible variation are considered. We focus on a role of the fine structure constant in modern physics and discuss precision tests of quantum electrodynamics. Different methods of a search for possible variations of fundamental constants are compared and those related to optical measurements are considered in detail.
