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

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.

We present a self-contained theoretical and computational framework for dynamics following photoexcitation in quantum dots near planar interfaces. A microscopic Hamiltonian parametrized by first-principles calculations is merged with a reduced density matrix formalism that allows for the prediction ... [Phys. Rev.

Numerical simulations of previous plane shock wave measurements on highly oriented pyrolytic graphite (HOPG), shocked to four peak stresses ranging from 27 to 50 GPa, are presented to address a long-standing question: When is the diamond phase formed in the shock-compressed graphite to diamond trans...

Recent experimental progress in coupling nanoscale conductors to superconducting microwave cavities has opened up for transport investigations of the deep quantum limit of light-matter interactions, with tunneling electrons strongly coupled to individual cavity photons.

We report the observation of optical near fields in a photonic waveguide of conductive indium tin oxide (ITO) using multiphoton photoemission electron microscopy (PEEM). Nonlinear two-photon photoelectron emission is enhanced at field maxima created by interference between incident 410-nm and cohere... [Phys. Rev. B 87, 205419 (2013)] Published Mon May 13, 2013

The real-time dynamics of local occupation numbers in a Hubbard model on a 6×6 square lattice is studied by means of the nonequilibrium generalization of the cluster-perturbation theory. The cluster approach is adapted to studies of two-dimensional lattice systems by using concepts of multiple-scatt... [Phys. Rev. B 87, 205118 (2013)] Published Mon May 13, 2013

We report on a comparative study of spin Hall related effects and magnetoresistance in YIG|Pt and YIG|Ta bilayers. These combined measurements allow to estimate the characteristic transport parameters of both Pt and Ta layers juxtaposed to yttrium iron garnet (YIG): the spin mixing conductance G↑↓ a... [Phys.

We study the Landau-Zener dynamics of a tunneling spin coupled to a torsional resonator. For strong spin-phonon coupling, when the oscillator frequency is large compared to the tunnel splitting, the system exhibits multiple Landau-Zener transitions. Entanglement of spin and mechanical angular moment... [Phys. Rev. B 87, 174418 (2013)] Published Mon May 13, 2013

We examine the influence of the main approximations employed in density functional theory descriptions of the solid phase of molecular hydrogen near dissociation.

Motivated by the nickel valence controversy in the perovskite nickelate RNiO3, we consider a one-dimensional underscreened Kondo chain consisting of alternating spin-1 (“nickel”) and electron (“oxygen”) sites, which in addition to the usual electron hopping and spin-spin interaction between the S=1 ...

ZrB2 is a nonsuperconducting Pauli paramagnetic crystallizing in the AlB2 structure. V substitution for Zr in Zr1−xVxB2 (0.01 ≤ x ≤ 0.1) at the few percentage level induces superconductivity with critical temperature reaching a maximum of 8.7 K for Zr0.96V0.04B2 near the solid solubility limit.
