EDITORS' SUGGESTION

Superconductivity from weak repulsion in hexagonal lattice systems

Rahul Nandkishore, Ronny Thomale, and Andrey V. Chubukov

Phys. Rev. B 89, 144501 (2014) - Published 7 April, 2014

The authors examine thoroughly the general cases in which superconductivity can arise on a hexagonal lattice with purely repulsive bare interactions, and find superconducting phases with unusual symmetries: $f$ - and chiral $d + i d$ -wave.

EDITORS' SUGGESTION

Search for spontaneous edge currents and vortex imaging in ${Sr}_{2} Ru O_{4}$ mesostructures

P. J. Curran, S. J. Bending, W. M. Desoky, A. S. Gibbs, S. L. Lee, and A. P. Mackenzie

Phys. Rev. B 89, 144504 (2014) - Published 9 April, 2014

Scanning Hall probe microscopy does not detect the “smoking gun” magnetic signatures of a chiral order parameter at the edges of Sr $_{2}$ RuO $_{4}$ microstructures, but it does reveal surprising changes in screening and bulk pinning above a threshold field strength.

EDITORS' SUGGESTION

Superconductivity from repulsion in LiFeAs: Novel $s$ -wave symmetry and potential time-reversal symmetry breaking

F. Ahn, I. Eremin, J. Knolle, V. B. Zabolotnyy, S. V. Borisenko, B. Büchner, and A. V. Chubukov

Phys. Rev. B 89, 144513 (2014) - Published 25 April, 2014

By analyzing the structure of the pairing interaction and superconducting gap in LiFeAs, and by reconciling calculations with experiment, the authors identify the most likely candidate as well as a new state that might exist at low temperatures.
