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…
Nuclear Data in Oklo and Time-Variability of Fundamental Coupling Constants
Yasunori Fujii, Akira Iwamoto, Tokio Fukahori +5
We re-examined Shlyakhter's analysis of the Sm data in Oklo. With a special care of minimizing contamination due to the inflow of the isotope after the end of the reactor activity,…
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…
Nonzero and a new type of the dissipative structure
Yasunori Fujii
We revisit the proposed theoretical model for a small but nonzero cosmological constant which seems supported increasingly better by recent observations. The model features two sca…
Brans-Dicke Cosmology Corrected for a Quantum Effect due to the Scalar-Matter Coupling
Yasunori Fujii
Cosmological solutions of the Brans-Dicke theory are investigated by including a quantum effect coming from 1-loop correction of matter fields that couple to the scalar field. As t…
A Mechanism for a small but nonzero cosmological constant
Yasunori Fujii
Based on a thoeretical model in which scalar fields play crucial roles, we propose a mechanism to better understand a cosmological constant expected to be small (nearly comparable…
