Can you get gravitons to behave like photons in laser?

Click For Summary

Discussion Overview

The discussion revolves around the possibility of creating gravitons in a manner analogous to photons, particularly in the context of a graviton laser. Participants explore theoretical frameworks and implications related to graviton behavior, amplification, and confinement, as well as the statistical properties of gravitons.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants question whether gravitons can be created similarly to photons, suggesting the need for an amplification medium and confinement to achieve coherent modes.
  • Others assert that gravitons, as hypothetical particles, are fundamentally different from photons and do not play a role in electron state changes.
  • There are discussions about the statistical properties of gravitons, with some suggesting they may exhibit Fermi statistics, which would challenge established theories.
  • A participant raises a question regarding the implications of graviton properties on its supersymmetric partner, the gravitino, and its potential classification as bosonic.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of creating a graviton laser and the fundamental properties of gravitons, indicating that multiple competing views remain and the discussion is unresolved.

Contextual Notes

There are limitations regarding the assumptions about graviton behavior and the implications of their statistical properties, which remain speculative and not empirically verified.

Is it possible to create gravitons the way photons are created, with electrons falling from quantized systems, or create graviton analogies to photon-lasers?

No. Gravitons (yet to be discovered) are the transmitters of gravity and nothing else. Changes in electron states are photon mediated - gravitons have no role.
 
If you want a graviton laser, you'll need a gain (amplification) medium (and a way to pump more energy into prepare this medium) and then a way to mostly confine the waves (so that a coherent mode is produced). Without the confinement, it's the analogy to a LED. No reason why it isn't possible in principle (though as pointed out, you'll need to construct it of systems of masses, rather than of electric charges).
 
Of course no one has measured a graviton.

While they are spin-2, the are some indications that they have Fermi statistics instead of Bose statistics. See section 4 of
http://www.arxiv.org/abs/gr-qc/0212096

This would be in violation of the spin statistics theorem, so it is a subject of some interest.
 
^ Would that have any knock on effects for the susy partner of the graviton, the gravitino. It's spin 3/2 but if it's 'normal' version is a fermion with spin 2, could it be bosonic?
