Limits to time variation of fundamental constants from atomic frequency standards Page 1
Limits to time variation of fundamental constants from comparisons of atomic frequency …

Fundamental constants play an important role in modern physics, being landmarks that
designate different areas. We call them constants, however, as long as we only consider …

Review of recent works devoted to the variation of the fine structure constant α, strong
interaction and fundamental masses (Higgs vacuum) is presented. The results from Big …

The choice, nature, classification, and precision of determination of fundamental physical
constants are described. The problem of temporal variations is also discussed. The need for …

Theories unifying gravity and other interactions suggest the possibility of spatial and
temporal variations of physical “constants.” Accuracy achieved for atomic optical frequency …

The question of a possible temporal variation of the fundamental constants was raised by
Paul Dirac in his" large number hypothesis" in 1937. Today it appears in the context of the …

of Theoretical Physics, Vol. 126, No. 6, December 2011 The Constancy of the Constants of …

The Sun's gravitational potential at Earth varies during a year due to varying Earth-Sun
distance. Comparing the results of very accurate measurements of atomic clock transitions …

In many theories beyond the Standard Model the quantities that we call “fundamental
constants” become space‐time dependent, leading to corresponding variation of atomic and …

A test of the position invariance (LPI) principle embodied in the Einstein equivalence
principle (EEP) has been performed via a ''null''gravitational redshift experiment. The rate of …
