If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Physics Colloquium (16/06/2022).



Abstract: The enduring challenge of reconciling quantum mechanics and general relativity is not helped by a lack of experimental guidance. Theoretical reconciliations, such as loop quantum gravity and string theory, seem to require unachievable experimental domains, and, while astrophysical data may one day provide guidance, the possibility of lab based experiments seems remote. Recently there have been suggestions for lab based tests of one aspect of the problem: gravitational decoherence. In this talk, I will review the concept of gravitational decoherence form Karolyhazy to Penrose and Diosi. I will discuss opto-mechanical proposals for constraining the decoherence rate by experiment. I will conclude with a discussion of a new approach based on single photonics that avoid many of the challenges that arise from tests involving particles with large rest mass.
