HIGHLIGHTED ARTICLES

EDITORS' SUGGESTION

Generalized Langevin equation: An efficient approach to nonequilibrium molecular dynamics of open systems

L. Stella, C. D. Lorenz, and L. Kantorovich

Phys. Rev. B 89, 134303 (2014) - Published 7 April, 2014

The authors present a very general integration scheme for simulating realistic dissipative systems with non-Markovian dynamics and colored noise. The key is a simple, efficient algorithm for the memory kernel.

EDITORS' SUGGESTION

Multiscale and multimodel simulation of Bloch-point dynamics

Christian Andreas, Attila Kákay, and Riccardo Hertel

Phys. Rev. B 89, 134403 (2014) - Published 3 April, 2014

The authors present a new approach to simulating the dynamical properties of point singularities in magnetization (Bloch points) with atomic resolution, by combining micromagnetic and spin-lattice simulations.

EDITORS' SUGGESTION

Lineshape of the singlet-triplet excitations in the dimer system Sr $_{3}$ Cr $_{2}$ O $_{8}$ to first order in the high-density $1 / z$ expansion

J. Jensen, D. L. Quintero-Castro, A. T. M. N. Islam, K. C. Rule, M. Månsson, and B. Lake

Phys. Rev. B 89, 134407 (2014) - Published 11 April, 2014

The authors study spin-triplet excitations in the strongly correlated spin-1/2 dimer system Sr $_{3}$ Cr $_{2}$ O $_{8}$ via inelastic neutron scattering. They find that the thermal broadening of the excitations can be accurately described by going beyond RPA via diagrammatic high-density $1 / z$ expansion.

EDITORS' SUGGESTION

Breakdown of the electron-spin motion upon reflection at metal-organic or metal-carbon interfaces

F. Djeghloul, P. Dey, A. Hallal, E. Urbain, S. Mahiddine, M. Gruber, D. Spor, M. Alouani, H. Bulou, F. Scheurer, and W. Weber

Phys. Rev. B 89, 134411 (2014) - Published 14 April, 2014

Spin-polarized electron scattering from ferromagnetic metal surfaces with submonolayer coverage by organic molecules shows complete breakdown of the angular spin motion of reflected electrons. This appears to be universal: independent of molecule, surface, electron energy, and other physical parameters.

EDITORS' SUGGESTION

Switching field distributions with spin transfer torques in perpendicularly magnetized spin-valve nanopillars

D. B. Gopman, D. Bedau, S. Mangin, E. E. Fullerton, J. A. Katine, and A. D. Kent

Phys. Rev. B 89, 134427 (2014) - Published 28 April, 2014

These experiments confirm the extent of applicability of an effective-barrier/temperature model for understanding the thermal stability of a nanopillar’s magnetization under spin-transfer torques.

EDITORS' SUGGESTION

Sudden reversal in the pressure dependence of $T_{c}$ in the iron-based superconductor CsFe $_{2}$ As $_{2}$ : A possible link between inelastic scattering and pairing symmetry

F. F. Tafti, J. P. Clancy, M. Lapointe-Major, C. Collignon, S. Faucher, J. A. Sears, A. Juneau-Fecteau, N. Doiron-Leyraud, A. F. Wang, X.-G. Luo, X. H. Chen, S. Desgreniers, Young-June Kim, and Louis Taillefer

Phys. Rev. B 89, 134502 (2014) - Published 4 April, 2014

The authors establish that pressure changes the pairing symmetry in $A$ Fe $_{2}$ As $_{2}$ ( $A$ = K, Cs) by tuning the competing inelastic scattering processes that favor different pairing states.
