APS Announces 149 New Outstanding Referees for 2012 February 28, 2012 The editors of the APS journals have selected 149 new Outstanding Referees for 2012, out of more than 60,000 currently active referees. Initiated in 2008, the highly selective Outstanding Referee program recognizes scientists who have been exceptionally helpful in assessing manuscripts for publication in the APS journals. Selections are based on two decades of records on the number, quality, and timeliness of referee reports. The 2012 honorees come from 31 different countries, with large contingents from the US, Germany, UK, Canada, and France. The decisions were difficult and there are many excellent referees who have yet to be recognized. By means of the program, APS expresses appreciation to all referees, whose efforts in peer review not only keep the standards of the journals at a high level, but in many cases also help authors to improve the quality and readability of their articles—even those that are not published by APS. For more information and a sortable listing of all Outstanding Referees, please visit publish.aps.org/OutstandingReferees. More News/Announcements

Editorial: Structured abstracts: A key to enhanced information transfer September 29, 2011 A primary goal of Physical Review C is to disseminate nuclear physics knowledge to research scientists working in the field. As a component of that effort, each published paper should carry a thoughtful, well organized abstract that conveys the main elements of the paper including the pertinent results.

Samuel A. Goudsmit Papers available online July 26, 2011 The Niels Bohr Library and Archives is pleased to announce that it has digitized the complete Samuel A. Goudsmit Papers
(1921–1979, 30 linear feet, approximately 67,000 images). The Goudsmit Papers are a major international collection of correspondence, research notebooks, reports, World War II science documents, and other material of Goudsmit, a Dutch physicist who spent most of his career in the US and was involved at the cutting-edge of physics for more than 50 years. Goudsmit became Editor of Physical Review in 1951 and was responsible for launching Physical Review Letters seven years later. In 1967 he was named APS Editor-in-Chief. More News/Announcements

APS Updates all Scanned Archival PDFs in our Physical Review Online Archive June 6, 2011 The American Physical Society is pleased to announce a refresh of all PDFs contained in the scanned portion of our Physical Review Online Archive (PROLA). APS was one of the first publishers to put our entire backfile online, completing the scanning process in May 2001. In those early days, APS opted to put our content online quickly and in an inexpensive manner that would then allow us to take advantage of any future improvements in technology. We have now completed the next step by partnering with Aquaforest. Using their Autobahn DX conversion software, we have efficiently reprocessed our entire scanned archive of approximately 250,000 articles, further compressing them and adding searchable text. Researchers will find these enhanced PDFs faster to download and much more convenient to navigate and read. APS is committed to ensuring the long-term availability and usability of all of the information that we publish. More News/Announcements

American Physical Society continues as MathJax Supporter May 13, 2011 The American Physical Society has announced that it will continue its support for the MathJax project for another year. APS was one of first organizations to become a MathJax Supporter, and is now one of the first to renew. The announcement represents an important milestone for MathJax, since support of organizations like APS over time is key to ensuring the project’s long-term success.

APS to Adopt Creative Commons Licensing and Publish Open Access Articles and Journals February 15, 2011 Authors in most Physical Review journals have a new alternative: to pay an article-processing charge whereby their accepted manuscripts will be available barrier-free and open access on publication. These manuscripts will be published under the terms of the Creative Commons Attribution 3.0 License (CC-BY), the most permissive of the CC licenses, granting authors and others the right to copy, distribute, transmit, and adapt the work, provided that proper credit is given. This new alternative is in addition to traditional subscription-funded publication; authors may choose one or the other for their accepted papers.

Viscosity of an ideal relativistic quantum fluid: A perturbative study
Giorgio Torrieri
We show that a quantized ideal fluid will generally exhibit a small but nonzero viscosity due to the backreaction of quantum sound waves on the background. We use an effective field theory expansion to estimate this viscosity to leading order in perturbation theory. We discuss our results and whethe... [Phys. Rev.

Search for spin-dependent short-range force between nucleons using optically polarized 3He gas

Wigner solution of the quark gap equation at nonzero current quark mass and partial restoration of chiral symmetry at finite chemical potential
Yu Jiang, Hao Gong, Wei-min Sun, and Hong-shi Zong
According to the generally accepted phase diagram of QCD, at low temperature and high baryon number density the chiral phase transition of QCD is of first order and the coexistence of the Nambu-Goldstone phase and the Wigner phase should appear. This is in conflict with the usual claim that the quar... [Phys. Rev. D 85, 034031 (2012)] Published Fri Feb 17, 2012
