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

We report a superconducting artificial atom with a coherence time of T2*=92 μs and energy relaxation time T1=70 μs. The system consists of a single Josephson junction transmon qubit on a sapphire substrate embedded in an otherwise empty copper waveguide cavity whose lowest eigenmode is dispersively ... [Phys. Rev.

The linear magnetoelectric response of Cr2O3 at zero temperature is calculated from first principles by tracking the change in magnetization under a macroscopic electric field. Both the spin and the orbital contributions to the induced magnetization are computed, and in each case the response is dec... [Phys. Rev. B 86, 094430 (2012)] Published Mon Sep 24, 2012

The Mott insulating state formed from bosons is ubiquitous in solid 4He, cold-atom systems, Josephson junction networks, and perhaps underdoped high-Tc superconductors. We predict that close to the quantum phase transition to the superconducting state, the Mott insulator is not at all as featureless... [Phys. Rev. B 86, 125129 (2012)] Published Fri Sep 21, 2012

Electrons in graphene, in addition to their spin, have two pseudospin degrees of freedom: sublattice and valley pseudospin. Valleytronics uses the valley degree of freedom as a carrier of information similarly to the way spintronics uses electron spin. We show how a double-barrier structure consisti... [Phys. Rev.

We study the coherent properties of transmission through Kondo impurities by considering an open Aharonov-Bohm ring with an embedded quantum dot. We develop a many-body scattering theory which enables us to calculate the conductance through the dot Gd, the transmission phase shift ϕt, and the normal... [Phys. Rev.

The edge of spin-unpolarized or spin-polarized ν=2/3 fractional quantum Hall states is predicted by the effective theory to support a backward-moving neutral mode in addition to a forward-moving charge mode. We study this issue from a microscopic perspective where these states are identified with an... [Phys. Rev. B 86, 115127 (2012)] Published Thu Sep 20, 2012

We study the interplay of structural and polar distortions in hexagonal YMnO3 and short-period PbTiO3/SrTiO3 (PTO/STO) superlattices by means of first-principles calculations at constrained electric displacement field D. We find that in YMnO3 the tilts of the oxygen polyhedra produce a robustly pola... [Phys. Rev. B 86, 094112 (2012)] Published Thu Sep 20, 2012

We investigate theoretically the prospects for using a magnetic nanoelectromechanical single-electron tunneling (NEM-SET) device as an electronic spin filter. We find that strong magnetic exchange forces on the net spin of the mobile central dot of the NEM-SET structure lead to spin-dependent mechan... [Phys. Rev.

We present a theory of the quasi-two-dimensional electron gas (2DEG) systems that appear near the surface of SrTiO3 when a large external electric field attracts carriers to the surface. We find that nonlinear and nonlocal screening by the strongly polarizable SrTiO3 lattice plays an essential role ... [Phys. Rev. B 86, 125121 (2012)] Published Mon Sep 17, 2012

In this work, we demonstrate that significant changes in electron temperature and nuclear spin polarization can be created by applying an electric current in a two-dimensional electron system at Landau level filling factor ν=1/2. The current induced effects on nuclear spins can be attributed to elec... [Phys. Rev. B 86, 115421 (2012)] Published Mon Sep 17, 2012

We study topological phases of interacting systems in two spatial dimensions in the absence of topological order (i.e., with a unique ground state on closed manifolds and no fractional excitations).

We construct a two-dimensional (2D) quantum spin model that realizes an Ising paramagnet with gapless edge modes protected by Ising symmetry.

The effect of a small substitution of Mn with Al in TbMnO3 has been studied. We report results of heat capacity, magnetization, and dielectric constant studies in TbMn1−xAlxO3 compounds (x ≤ 0.1).
