New design of gravitational wave detectors
Xavier Jaén, Pere Talavera
We propose a novel approach to detect gravitational waves based on a semi-rigid detector. The approach relies upon the time delay that the light takes to travel from a fixed mirror…
Rigid covariance, equivalence principle and Fermi rigid coordinates:gravitational waves
Xavier Jaén
For a given space-time and for an arbitrary time-like geodesic, we analyze the conditions for the construction of Fermi coordinates so that they are also rigid covariant. We then a…
Rigid covariance as a natural extension of Painlevé--Gullstrand space-times: gravitational waves
Xavier Jaén, Alfred Molina
The group of rigid motions is considered to guide the search for a natural system of space-time coordinates in General Relativity. This search leads us to a natural extension of th…
On the meaning of Painlevé--Gullstrand synchronization
Xavier Jaén, Alfred Molina
Following on from two recent papers, here we examine the relationship between Newtonian gravitation and general relativity in more depth. This allows us to define a scalar potentia…
Homothetic motions and Newtonian cosmology
Xavier Jaén, Alfred Molina
We consider the homothetic motion group. We construct a homothetic covariant Newtonian gravitation theory which unifies inertial homothetic forces and gravitational fields. This is…
Rigid motions and generalized Newtonian gravitation. Lost in Translation
Xavier Jaén, Alfred Molina
We try to lay down the foundations of a Newtonian theory where inertia and gravitational fields appear in a unified way aiming to reach a better understanding of the general relati…
