Weber-like interactions and energy conservation
(1997)
Velocity-dependent forces varying as k(rˆ/r)(1−μr˙2+γrr¨) (such as Weber force), here calledWeber-like forces, are examined from the point of view of energy conservation and it is proved that they are conservative if and ...
Gravitational Waves in Scalar-Tensor-Vector Gravity Theory
(Mdpi, 2021-01-01)
In this paper, we study the properties of gravitational waves in the scalar-tensor-vector gravity theory. The polarizations of the gravitational waves are investigated by analyzing the relative motion of the test particles. ...

Gravitational Effects in the Collision of Elasto-Viscoplastic Drops on a Vertical Plane
(Mdpi, 2020-06-01)
The collision of drops in a solid substrate is an interesting problem with several practical applications. When the drop is made of a complex fluid the problem presents numerical challenges due to the interaction of the ...
Primordial gravitational waves amplification from causal fluids
(American Physical Society, 2018-01)
We consider the evolution of the gravitational wave spectrum for super-Hubble modes in interaction with a relativistic fluid, which is regarded as an effective description of fluctuations in a light scalar minimally coupled ...
Entropic forces and Newton's gravitation
(Multidisciplinary Digital Publishing Institute, 2020-02)
Our subject of interest here is entropic forces, as re-interpreted by Verlinde with reference to gravitation, that is, by appealing to Verlinde’s conception of an entropic (statistically emergent) gravity advanced in ...
Inflationary gravitational waves from unified spinor fields
(Springer, 2018-12)
Recent observations of Gravitational Waves (GW) generated by black-hole collisions have opened a new window to explore the universe in diverse scales. Detection of primordial gravitational waves is expected to happen in ...
The equivalence principle revisited
(Kluwer Academic/plenum Publ, 2003-04-01)
A precise fomulation of the strong Equivalence Principle is essential to the understanding of the relationship between gravitation and quantum mechanics. The relevant aspects are reviewed in a context including General ...
