Interface superconductivity: Get it strained

Fakher F. Assaad

Published online: 02 November 2014 | doi:10.1038/nphys3161

Stretching a sheet of graphene could induce a superconducting state. Similar strain-induced superconductivity may be realized at the interface between a topological crystalline insulator and a trivial band insulator.

Atomic solitons: These crashing waves

Thomas P. Billam & Christoph Weiss

Published online: 02 November 2014 | doi:10.1038/nphys3162

Solitons in attractive Bose–Einstein condensates are mesoscopic quantum objects that may prove useful as tools for precision measurement. A new experiment shows that collisions of matter-wave bright solitons depend crucially on their relative phase.

Collisions of matter-wave solitons

Jason H. V. Nguyen, Paul Dyke, De Luo, Boris A. Malomed & Randall G. Hulet

Published online: 02 November 2014 | doi:10.1038/nphys3135

Atomic matter waves provide a controllable platform for studying the behaviour of solitons. In a lithium condensate, a characterization of the dynamics of collisions between solitons reveals a dependence on their relative phases.

Strain-induced partially flat band, helical snake states and interface superconductivity in topological crystalline insulators

Evelyn Tang & Liang Fu

Published online: 02 November 2014 | doi:10.1038/nphys3109

In topological crystalline insulators, crystal symmetries give rise to particular electronic structures. As now shown, strain further induces pseudo-Landau states in IV–VI heterostructures—a mechanism possibly responsible for the superconductivity observed in such systems.

Momentum-space imaging of Cooper pairing in a half-Dirac-gas topological superconductor

Su-Yang Xu, Nasser Alidoust, Ilya Belopolski, Anthony Richardella, Chang Liu, Madhab Neupane, Guang Bian, Song-Hsun Huang, Raman Sankar, Chen Fang, Brian Dellabetta, Wenqing Dai, Qi Li, Matthew J. Gilbert, Fangcheng Chou, Nitin Samarth & M. Zahid Hasan

Published online: 02 November 2014 | doi:10.1038/nphys3139

Supersymmetry and Majorana fermions that are their own antiparticles are both concepts from particle physics that may become testable in condensed-matter systems. The observation of Cooper pairs in a helical Dirac gas brings this goal a step closer.

Rydberg atoms: Two to tango

Robert Löw

Published online: 26 October 2014 | doi:10.1038/nphys3153

The old adage that you can't tango alone is certainly true for humans. But recent experiments show that it may also be applicable to Rydberg atoms, which keep a beat through the coherent exchange of energy.

Evidence of Andreev bound states as a hallmark of the FFLO phase in κ-(BEDT-TTF)2Cu(NCS)2

H. Mayaffre, S. Krämer, M. Horvatić, C. Berthier, K. Miyagawa, K. Kanoda & V. F. Mitrović

Published online: 26 October 2014 | doi:10.1038/nphys3121

A Fulde–Ferrell–Larkin–Ovchinnikov superconductor comprises pairs of fermions with non-zero momentum, which form alternating superconducting and normal regions in a magnetic field. NMR measurements now provide microscopic evidence for such a state.

Coherent dipole–dipole coupling between two single Rydberg atoms at an electrically-tuned Förster resonance

Sylvain Ravets, Henning Labuhn, Daniel Barredo, Lucas Béguin, Thierry Lahaye & Antoine Browaeys

Published online: 26 October 2014 | doi:10.1038/nphys3119

Rydberg atoms offer an avenue for quantum simulation of many-body problems, but evidence for the coherent nature of their interaction is indirect. An externally-tuned resonance now reveals coherent oscillations between two single Rydberg atoms.

Cooperative coupling of ultracold atoms and surface plasmons

Christian Stehle, Claus Zimmermann & Sebastian Slama

Published online: 26 October 2014 | doi:10.1038/nphys3129

Coupling the fluorescence of cold atoms to plasmons propagating on a gold surface offers a means of controlling the radiation from optical emitters without the need for a cavity.

The dynamics of a doped hole in a cuprate is not controlled by spin fluctuations

Hadi Ebrahimnejad, George A. Sawatzky & Mona Berciu

Published online: 19 October 2014 | doi:10.1038/nphys3130

A variational approach for a three-band model provides deeper insights into the dynamics of a hole doped into an antiferromagnetic layer, with important implications for theories of high-temperature superconductivity.

Until print versions of AOP papers are published, they should be cited in the style "Author(s) Nature Physics advance online publication, day month year (doi:10.1038/nphysXXXXX)". Once the print version (identical to the AOP) is published, it should be cited as follows: "Author(s) Nature Physics volume, page (year); advance online publication, (doi:10.1038/nphysXXXXX)".
