The determination of the fine structure constant α and the search for its possible variation are considered. We focus on the 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. 
Variation of the constants in the late and early universe
Recent key observational results on the variation of fine structure constant, the proton to electron mass ratio and the gravitational constant are reviewed. The necessity to substantiate the dark
Quantum electrodynamics, high-resolution spectroscopy and fundamental constants
Abstract Recent progress in high-resolution spectroscopy has delivered us a variety of accurate optical results, which can be used for the determination of the atomic fundamental constants and for

The relations between the constants, the tests of the local position invariance and of the universality of free fall are detailed, and the unification mechanisms and the relation between the variation of different constants are described.
Cosmological Evolution of Fundamental Constants: From Theory to Experiment
In this paper we discuss a possible cosmological time evolution of fundamental constants from the theoretical and experimental point of views. On the theoretical side, we explain that such a
Magneto-optical trapping of neutral mercury
Abstract We report on the cooling of neutral mercury in a magneto-optical trap utilizing the spin forbidden 1S0 → 3P1 transition at 253.7 nm. We trapped two Hg isotopes, i.e. the bosonic 202Hg and
Dimensions and units in electrodynamics
We sketch the foundations of classical electrodynamics, in particular the transition that took place when Einstein, in 1915, succeeded to formulate general relativity. In 1916 Einstein demonstrated
Recent developments in premetric
Classical electrodynamics can be based on the conservation laws of electric charge and magnetic flux. Both laws are independent of the metric and the linear connection of spacetime. Within the


Some possibilities for laboratory searches for variations of fundamental constants
We consider different options for the search for possible variations of the fundamental constants. We give a brief overview of the results obtained with several methods. We discuss their advantages
Direct test of the constancy of fundamental nuclear constants
THE possibility that fundamental nuclear constants may vary slowly while the Universe expands has been discussed by several authors1–5. I try here to show that the well known resonance properties of
Progress in helium fine-structure calculations and the fine-structure constant
The long-term goal of this work is to determine the fine-structure constant α from a comparison between theory and experiment for the fine-structure splittings of the helium 1s2p 3PJ states. All
Time Variation of the Fundamental "Constants" and Kaluza-Klein Theories
Time dependence of the fundamental ''constants'' is examined within the framework of Kaluza-Klein theories. Relationships among low-energy couplings and masses are derived. It is suggested that
The fundamental constants and their variation: observational and theoretical status
This article describes the various experimental bounds on the variation of the fundamental constants of nature. After a discussion of the role of fundamental constants, their definition and link with
New determination of the electron's mass.
A new independent value for the electron's mass in units of the atomic mass unit is presented, m(e) = 0.000 548 579 909 2(4) u. The value is obtained from our recent measurement of the g factor of
The cosmological evolution of the nucleon mass and the electroweak coupling constants
Abstract. Starting from astrophysical indications that the fine structure constant might undergo a small cosmological time shift, we discuss the implications of such an effect from the point of view
Calculations of the relativistic effects in many-electron atoms and space-time variation of fundamental constants
Theories unifying gravity and other interactions suggest the possibility of spa- tial and temporal variation of physical "constants" in the Universe. Detection of high-redshift absorption systems
