APS Announces 142 New Outstanding Referees for 2013 February 6, 2013 The editors of the APS journals have selected 142 new Outstanding Referees for 2013, 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 2013 honorees come from 27 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 listing of all Outstanding Referees, please visit publish.aps.org/OutstandingReferees. More News/Announcements

APS Partners with ORCID For Launch October 16, 2012 Today ORCID opened its registry allowing researchers in all fields and from around the world to distinguish themselves by registering for their own unique identifier. APS has been a long-time supporter of ORCID and, as one of the official Launch Partners, we have updated our author profile application so that authors may register their ORCID within our database of authors and referees. Widespread adoption of ORCID identifiers will improve the scholarly record and help researchers receive proper credit for all of their contributions. To get started, simply visit the APS Author Profile application. More News/Announcements

Electrodynamic response and stability of molecular crystals
Bohdan Schatschneider, Jian-Jie Liang, Anthony M. Reilly, Noa Marom, Guo-Xu Zhang, and Alexandre Tkatchenko
We show that electrodynamic dipolar interactions, responsible for long-range fluctuations in matter, play a significant role in the stability of molecular crystals. Density functional theory calculations with van der Waals interactions determined from a semilocal “atom-in-a-molecule” model result in... [Phys. Rev. B 87, 060104 (2013)] Published Thu Feb 28, 2013

Skyrmion dynamics in multiferroic insulators
Ye-Hua Liu, You-Quan Li, and Jung Hoon Han
The recent discovery of a Skyrmion crystal phase in an insulating multiferroic compound Cu2OSeO3 calls for new ways and ideas to manipulate the Skyrmions in the absence of spin transfer torque from the conduction electrons. It is shown here that the position-dependent electric field, pointed along t... [Phys. Rev. B 87, 100402 (2013)] Published Wed Mar 13, 2013
Prediction of two-dimensional diluted magnetic semiconductors: Doped monolayer MoS2 systems
Y. C. Cheng, Z. Y. Zhu, W. B. Mi, Z. B. Guo, and U. Schwingenschlögl
Using first-principles calculations, we propose a two-dimensional diluted magnetic semiconductor: monolayer MoS2 doped by transition metals. Doping of transition metal atoms from the IIIB to VIB groups results in nonmagnetic states, since the number of valence electrons is smaller or equal to that o... [Phys. Rev.

We have observed a ferromagnetic-induced piezoresistance component in a micromechanical cantilever integrated with a GaMnAs piezoresistor. The temperature and the magnetic-field dependence of the piezoresistance around the ferromagnetic transition reveal that the piezoresistance is modulated by ferr... [Phys. Rev.

Layer-layer coupling plays a critical role in defining the physical properties of few-layer graphene. With respect to vibrations, for each layer thickness N, interlayer coupling creates a set of N−1 out-of-plane layer breathing modes (ZO′) with finite frequencies at the zone center.
