A new estimate of the mass of the gravitational scalar field for Dark Energy
Yasunori Fujii
A new estimate of the mass of the pseudo dilaton is offered by following the funda- mental nature that a massless Nambu-Goldstone boson, called a dilaton, in the Einstein frame acq…
Is the zero-point energy a source of the cosmological constant?
Yasunori Fujii
We discuss how we remove a huge discrepancy between the theory of a cosmological constant, due to the zero-point energies of matter fields, and the observation. The technique of di…
An approach toward the laboratory search for the scalar field as a candidate of Dark Energy
Yasunori Fujii, Kensuke Homma
The observed accelerating universe indicates the presence of Dark Energy which is probably interpreted in terms of an extremely light gravitational scalar field. We suggest a way t…
A Laboratory Search for Dark Energy
Yasunori Fujii, Kensuke Homma
The discovery of the accelerating universe indicates strongly the presence of a scalar field which is not only expected to solve today's version of the cosmological constant proble…
Accelerating universe and the time-dependent fine-structure constant
Yasunori Fujii
Theoretical background of our proposed relation between the accelerating universe and the time-variability of the fine-structure constant is discussed, based on the scalar-tensor t…
How successful can the scalar-tensor theory be in understanding the accelerating universe?
Yasunori Fujii
The accelerating universe is closely related to today's version of the cosmological constant problem; fine-tuning and coincidence problems. We show how successfully the scalar-tens…
