Geophysical constraint on a relic background of the dilatons
Sachie Shiomi
According to a scenario in string cosmology, a relic background of light dilatons can be a significant component of the dark matter in the Universe. A new approach of searching for…
Testing gravitational physics with superconducting gravimeters
Sachie Shiomi
Superconducting gravimeters are the most sensitive instruments to measure surface gravity changes at low frequencies. Currently, about twenty five superconducting gravimeters are o…
Geophysical test of the universality of free-fall
Sachie Shiomi
We point out that the universality of free-fall can be tested by observing surface-gravity changes of the Earth. The Earth's inner core is weakly coupled to the rest part of the Ea…
Proposal for a geophysical search for dilatonic waves
Sachie Shiomi
We propose a new method of searching for the composition-dependent dilatonic waves, predicted by unified theories of strings. In this method, Earth's surface-gravity changes due to…
Acceleration disturbances due to local gravity gradients in ASTROD I
Sachie Shiomi
The Astrodynamical Space Test of Relativity using Optical Devices (ASTROD) mission consists of three spacecraft in separate solar orbits and carries out laser interferometric rangi…
Acceleration disturbances and requirements for ASTROD I
Sachie Shiomi, Wei-Tou Ni
ASTRODynamical Space Test of Relativity using Optical Devices I (ASTROD I) mainly aims at testing relativistic gravity and measuring the solar-system parameters with high precision…
