Fundamental Physics in Space: A Quantum-Gravity Perspective
@article{AmelinoCamelia2004FundamentalPI, title={Fundamental Physics in Space: A Quantum-Gravity Perspective}, author={Giovanni Amelino-Camelia}, journal={General Relativity and Gravitation}, year={2004}, volume={36}, pages={539-560} }
I consider the possibility that space experiments be used to search for quantum properties of spacetime. On the basis of recent quantum-gravity results, I argue that insight on some quantum properties of spacetime can be obtained with experiments planned for the International Space Station, such as AMS and EUSO, and with satellite gamma-ray telescopes, such as GLAST.

Local spacetime curvature effects on quantum orbital angular momentum
- Physics
- 2011
This paper claims that local spacetime curvature can nontrivially contribute to the properties of orbital angular momentum in quantum mechanics. Of key importance is the demonstration that an…
Comment on 'Large-scale non-locality in "doubly special relativity" with an energy-dependent speed of light'
- Physics
- 2003
We show that some of the recent results reported in gr-qc/0308049 are based on assumptions which are in contrast with general properties of ``Doubly Special Relativity'' and/or with Planck-scale…
Emergent rainbow spacetimes: Two pedagogical examples
- Physics
- 2007
There is a possibility that spacetime itself is ultimately an emergent phenomenon, a near-universal "low-energy long-distance approximation", similar to the way in which fluid mechanics is the…
Exotic Galilean Symmetry and Non-Commutative Mechanics ?
- Physics
- 2010
Some aspects of the "exotic" particle, associated with the two-parameter central extension of the planar Galilei group are reviewed. A fundamental property is that it has non-commuting position…
Ultimate decoherence border for matter-wave interferometry.
- PhysicsPhysical review letters
- 2006
A quantitative characterization of an ultimate decoherence border for matter-wave interferometry using larger and larger molecules is given in terms of figures involving the gravitational environment as well as the sensitivity of the interferometer to gravitational waves.
Spectral line broadening and angular blurring due to spacetime geometry fluctuations
- Physics
- 2006
We treat two possible phenomenological effects of quantum fluctuations of spacetime geometry: spectral line broadening and angular blurring of the image of a distance source. A geometrical…
Enhanced geometry fluctuations in Minkowski and black hole spacetimes

Gravity waves — predicted by Einstein's general theory of relativity, but not yet detected — may one day reveal more about the very early Universe. They may also test theories of quantum gravity…
Loop quantum gravity and ultrahigh energy cosmic rays

it has been suggested that quantum-gravitational effects may be playing a decisive role in the propagation of ultrahigh energy cosmic rays. In this article we take the loop quantum gravity approach.…
Quantum Gravity and Minimum Length

The existence of a fundamental scale, a lower bound to any output of a position measurement, seems to be a model-independent feature of quantum gravity. In fact, different approaches to this theory…
Reflections on the Fate of Spacetime

Our basic ideas about physics went through several upheavals early this century. Quantum mechanics taught us that the classical notions of the position and velocity of a particle were only…
Testing the principle of equivalence with neutrino oscillations.
- PhysicsPhysical review. D, Particles and fields

The laboratory limits on the neutrino oscillation process can be interpreted as tests of the equivalence principle in the quantum-relativistic regime, and put severe constraints on a maximal violation of this Principle in the case of massless neutrinos coupled to the Earth's gravitational field.
