The Potential of Continuous, Local Atomic Clock Measurements for Earthquake Prediction and Volcanology
Mihai Bondarescu, Ruxandra Bondarescu, Philippe Jetzer +1
Modern optical atomic clocks along with the optical fiber technology currently being developed can measure the geoid, which is the equipotential surface that extends the mean sea l…
Atomic clocks as a tool to monitor vertical surface motion
Ruxandra Bondarescu, Andreas Schärer, Andrew Lundgren +4
Atomic clock technology is advancing rapidly, now reaching stabilities of , which corresponds to resolving cm in equivalent geoid height over an integration…
The Physics of the Far Future
Ruxandra Bondarescu, Andrew P. Lundgren, Mihai Bondarescu
We observe the past and present of the universe, but can we predict the far future? Observations suggest that in thousands of billions of years from now most matter and radiation w…
Merging Gravitation with Thermodynamics to Understand Cosmology
Andrew P. Lundgren, Ruxandra Bondarescu, Mihai Bondarescu
We discuss the evolution of the universe in the context of the second law of thermodynamics from its early stages to the far future. Cosmological observations suggest that most mat…
Geophysical applicability of atomic clocks: direct continental geoid mapping
Ruxandra Bondarescu, Mihai Bondarescu, György Hetényi +3
The geoid is the true physical figure of the Earth, a particular equipotential surface of the gravity field of the Earth that accounts for the effect of all subsurface density vari…
Depressing de Sitter in the Frozen Future
Andrew P. Lundgren, Mihai Bondarescu, Ruxandra Bondarescu
In this paper we focus on the gravitational thermodynamics of the far future. Cosmological observations suggest that most matter will be diluted away by the cosmological expansion,…
