Gravitation as Anholonomy [PDF]
General Relativity and Gravitation, 2003 A gravitational field can be seen as the anholonomy of the tetrad fields. This is more explicit in the teleparallel approach, in which the gravitational field-strength is the torsion of the ensuing Weitzenboeck connection. In a tetrad frame, that torsion

Gravitation and Nonlocality [PDF]
2001: A Relativistic Spacetime Odyssey, 2001 The physical basis of the standard theory of general relativity is examined and a nonlocal theory of accelerated observers is described that involves a natural generalization of the hypothesis of locality.

Gravitational Fields and Gravitational Waves [PDF]
Physics Essays, 2021 Abstract For any object with finite velocity, the relative velocity between them will affect the effect between them. This effect can be called the chasing effect (general Doppler effect). LIGO discovered gravitational waves and measured the speed of gravitational waves equal to the speed of light c. Gravitational waves are generated due to the

Gravitation and Thermodynamics [PDF]
Nature, 1917 DR. TODD (NATURE, March 1) suggests that when one gravitative mass approaches another it acquires heat. This might occur when, as is usually (but not always) the case, the body moves up the gradient of potential; for then the energy of field displaced by the body would increase.

Gravitational decoherence [PDF]
Classical and Quantum Gravity, 2017 We discuss effects of loss of coherence in low energy quantum systems caused by or related to gravitation, referred to as gravitational decoherence. These effects, resulting from random metric fluctuations, for instance, promise to be accessible by relatively inexpensive table-top experiments, way before the scales where true quantum gravity effects ...

Physical Review D, 2019 Particles in a yet unexplored dark sector with sufficiently large mass and small gauge coupling may form purely gravitational atoms (quantum gravitational bound states) with a rich phenomenology. In particular, we investigate the possibility of having an observable signal of gravitational waves or ultra high energy cosmic rays from the decay of ...

Journal of High Energy Physics, 2023 Abstract We consider four-dimensional general relativity with vanishing cosmological constant defined on a manifold with a boundary. In Lorentzian signature, the timelike boundary is of the form σ × ℝ, with σ a spatial two-manifold that we take to be either flat or S2. In Euclidean signature we take the boundary to be S2 × S1.
