Accelerating universe, WEP violation and antihydrogen atoms
Yasunori Fujii
Apart from the suspected violation of the CPT invariance, we might expect if the measurements of antihydrogen atoms provide testing Weak Equivalence Principle (WEP) in the gravitat…
Conformal transformation in the scalar-tensor theory applied to the accelerating universe
Yasunori Fujii
The scalar-tensor theory is plagued by nagging questions if different conformal frames, in particular the Jordan and Einstein conformal frames, are equivalent to each other. As a c…
Some aspects of the scalar-tensor theory
Yasunori Fujii
The scalar-tensor theory of gravitation has been and still is one of the most widely discussed "alternative theories" to General Relativity (GR). Despite nearly half a century of i…
Varying Fine-Structure Constant and the Cosmological Constant Problem
Yasunori Fujii
We start with a brief account of the latest analysis of the Oklo phenomenon providing the still most stringent constraint on time-variability of the fine- structure constant . C…
Mass of the dilaton and the cosmological constant
Yasunori Fujii
One might raise a question if the gravitational scalar field (dilaton) mediates a finite-range force between local objects still behaving globally as being massless to implement th…
What can we do on gravity with antihydrogens?
Yasunori Fujii
We discuss the implications of the proposed gravitational redshift experiment on antihydrogens. We show that the result should be the same as on hydrogens in spite of different fre…
