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: Electromechanics for thermodynamics at the nano-scale by Natalia Ares [refresh]
FQXI's Natalia Ares describes how quantum physicists are seeking to better understand how thermodynamics operates at small scales. Here, fluctuations are significant and quantum behaviour arises. This may reveal possibilities for entirely novel technologies.
We can explore thermodynamics in this limit by combining exquisite control over mechanical degrees of freedom and the quantum states of confined electrons. Ares describes how to detect the displacement of a carbon nanotube approaching the standard quantum limit near the phonon ground state [1-2]. With quantum dots embedded in a carbon nanotube, her team has been able to explore the impact of electron tunnelling in the nanotube’s mechanical energy, evidenced by the excitation of coherent self oscillations [3]. Ares discusses the potential of these findings to pave the way for experiments on quantum thermodynamics, in particular, for direct measurements of work exchange.
