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.

TOPIC: Philipp Hoehn - (Quantum) frame covariance in gauge systems and gravity by Phillip Hoehn [refresh]
Recent years have seen a resurging interest in dynamical reference frames in quantum foundations, gauge theories and gravity. I will discuss some of these developments by drawing connections between the different fields. For example, I will discuss how the so-called `paradox of the third particle’ in quantum foundations can be resolved by understanding it from the perspective of boundaries in gauge theories. Conversely, I will comment on how one can understand aspects of edge modes in finite region gauge theories from the point of view of reference frames. More generally, I will explain how quantum frame covariance leads to a quantum relativity of subsystems, which entails that the notion of subsystem locality becomes dependent on the choice of frame, as do associated physical properties such as correlations and entropies. I will suggest implications of this for the interpretation of gauge-invariant observables in gauge theories and gravity.
