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 http://publish.aps.org/OutstandingReferees.

February 24, 2012 At the end of February 2012, I will be stepping away as Senior Editor of Physical Review B, a full-time position I have held since July 1969. I will, however, be continuing as an editor of the journal in a less expansive role. Dr. Laurens Molenkamp, based in the University of Würzburg, has been appointed Senior Editor beginning 1 March 2012. I wish him well in undertaking the management of this great journal.

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.

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

Electrons and holes in a semiconductor form hydrogen-atom-like bound states, called excitons. At high electron-hole densities the attractive Coulomb force becomes screened and excitons can no longer exist. BCS theory predicts that at such high densities cooperative many-body effects can at low tempe... [Phys. Rev. B 85, 195206 (2012)] Published Tue May 15, 2012

The phantom force is an apparently repulsive force, which can dominate the atomic contrast of an AFM image when a tunneling current is present. We described this effect with a simple resistive model, in which the tunneling current causes a voltage drop at the sample area underneath the probe tip. Be... [Phys. Rev.

We present ac susceptibility and specific-heat measurements taken on samples of LiHoxY1−xF4 in the dilute limit: x=0.018, 0.045, 0.080, and 0.12. Susceptibility measurements show glassy behavior including wide absorption spectra that continually broaden with decreasing temperature. Dynamical scaling... [Phys. Rev.

The competition between intertube hopping processes and density-density interactions is investigated in one-dimensional quantum dipolar bosons systems of N coupled tubes at zero temperature. Using a phenomenological bosonization approach, we show that the resulting competition leads to an exotic qua... [Phys. Rev. B 85, 195121 (2012)] Published Thu May 10, 2012

We show that a three-dimensional topological insulator doped with magnetic impurities in the bulk can have a regime where the surface is magnetically ordered but the bulk is not. This is in contrast to conventional materials where bulk ordered phases are typically more robust than surface ordered ph... [Phys. Rev. B 85, 195119 (2012)] Published Thu May 10, 2012

We derive an approximate analytical solution of the self-consistency equations of the bosonic dynamical mean-field theory (B-DMFT) in the strong-coupling limit. The approach is based on a linked-cluster expansion in the hybridization function of normal bosons around the atomic limit. The solution is... [Phys. Rev.

We systematically investigate magnetic reversal of permalloy islands in a square spin-ice geometry with in situ Lorentz microscopy.

Superlattices (SLs) in monolayer and bilayer graphene, formed by spatially periodic potential variations, lead to a modified bandstructure with extra finite-energy and zero-energy Dirac fermions with tunable anisotropic velocities.

It has been suggested that after being gapped by a small symmetry-breaking field, the Majorana quasiparticles localized on the surface of a class DIII topological insulator will exhibit a thermal Hall effect that arises from a gravitational Chern-Simons term.

A number of recent experiments have used torsional oscillators to study the behavior of solid helium. The oscillator frequencies increased at temperatures below 200 mK, an effect attributed to decoupling of a fraction of the helium mass—the signature of a “supersolid” phase. However, helium's shear ... [Phys. Rev. B 85, 180501 (2012)] Published Thu May 3, 2012

We have experimentally studied the nonlinear nature of electrical conduction in monolayer graphene devices on silica substrates. This nonlinearity manifests itself as a nonmonotonic dependence of the differential resistance on applied dc voltage bias across the sample. At temperatures below ∼70 K, t... [Phys. Rev.
