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: Measuring, erasing or cooling quantum systems by Marcus Huber [refresh]
TOPIC: Measuring, erasing or cooling quantum systems by Marcus Huber [refresh]
Abstract: The thermodynamic costs and limitations of measuring, erasing or cooling quantum systems have been studied within different paradigms. Projective measurements, perfect erasure or exact ground state cooling are of course limited by the third law of thermodynamics and cannot be achieved without infinite resources, which present differently in each paradigm. I will briefly cover some desirable properties of measurements and talk about notions of cooling beyond equilibrated systems. Then I will present a framework that unifies many approaches and allows to bound achievable cooling using general properties of the system used to refrigerate, giving insight into the relation between complexity, cooling and energy.
