To take full advantage, however, they need a subtle but important shift in mindset. Commentary Top The physics of data   pp718 - 719 Jeff Byers doi:10.1038/nphys4202 Physicists are accustomed to dealing with large datasets, yet they are fortunate in that the quality of their experimental data is very good. The onset of big data has led to an explosion of datasets with a far more complex structure — a development that requires new tools and a different mindset. Thesis Top Simple yet successful   p720 Mark Buchanan doi:10.1038/nphys4228 Books and Arts Top Music: Last night a DJ went to space   p721 Federico Levi doi:10.1038/nphys4226 Research Highlights Top Quantum thermodynamics: In the demon's mind | Quantum communication: Satellite to ground control | Plasma physics: Turbulent tabletops | Ultracold gases: A test of scaling | Majorana modes: The new black News and Views Top Gravitational-wave detection: Entanglement at work   pp723 - 724 Raffaele Flaminio doi:10.1038/nphys4152 The Einstein–Podolsky–Rosen type of quantum entanglement can be used to improve the sensitivity of laser interferometer gravitational-wave detectors beyond the quantum limit.

Quantum simulation: Probing information scrambling   pp724 - 726 Monika Schleier-Smith doi:10.1038/nphys4165 Quantum information encoded in one of many interacting particles quickly becomes scrambled. A set of tools for tracking this process is on its way. See also: Article by Gärttner et al. Van der waals heterostructures: Exciting double bilayers   pp726 - 728 Koji Muraki doi:10.1038/nphys4163 An excitonic Bose–Einstein condensate has so far been realized only in particular semiconductor heterostructure setups. Now, experiments show that such condensates can form in double graphene bilayers separated by hexagonal boron nitride. See also: Letter by Liu et al. | Letter by Li et al. Cell mechanics: The benefits of getting high   pp728 - 729 Klaus Kroy doi:10.1038/nphys4128 Standard rheology tells us how a cell responds to deformation. But ramping up the frequency reveals more about its internal dynamics and morphology, mapping a route to improved drug treatments — and possible insight into the malignancy of cancers.

J. DeSalvo, Krutik Patel and Cheng Chin doi:10.1038/nphys4130 The emergence of Efimov states in ultracold atomic systems is expected to have a universal behaviour, but a new experimental study defies this expectation, reporting a clear deviation around a narrow Feshbach resonance. Topological triplon modes and bound states in a Shastry–Sutherland magnet   pp736 - 741 P. A. McClarty, F. Krüger, T. Guidi, S. F. Parker, K. Refson et al. doi:10.1038/nphys4117 A detailed experimental investigation on the spin excitations in SrCu2(BO3)2 under an external magnetic confirms the existence of topological triplon modes in this experimental realization of the Shastry–Sutherland model. Multidimensional entropy landscape of quantum criticality   pp742 - 745 K. Grube, S. Zaum, O. Stockert, Q. Si and H. v. Löhneysen doi:10.1038/nphys4113 Thermal-expansion measurements of CeCu6–xAux reveal the thermodynamic landscape of this material's entropy, offering insights into the behaviour of quantum critical fluctuations as the system approaches its quantum critical point. Quantum Hall drag of exciton condensate in graphene   pp746 - 750 Xiaomeng Liu, Kenji Watanabe, Takashi Taniguchi, Bertrand I. Halperin and Philip Kim doi:10.1038/nphys4116 An electronic double layer, subjected to a high magnetic field, can form an exciton condensate: a Bose–Einstein condensate of Coulomb-bound electron–hole pairs. Now, exciton condensation is reported for a graphene/boron-nitride/graphene structure. See also: News and Views by Muraki Excitonic superfluid phase in double bilayer graphene   pp751 - 755 J. I. A. Li, T. Taniguchi, K. Watanabe, J. Hone and C. R. Dean doi:10.1038/nphys4140 Strongly interacting bosons have been predicted to display a transition into a superfluid ground state, similar to Bose–Einstein condensation. This effect is now observed in a double bilayer graphene structure, with excitons as the bosonic particles.

K. Feofanov and T. J. Kippenberg doi:10.1038/nphys4121 A microwave cavity optomechanics experiment investigates the interplay between the electromagnetic and mechanical modes and how their roles can be reversed in engineered dissipation. Möbius Kondo insulators   pp794 - 798 Po-Yao Chang, Onur Erten and Piers Coleman doi:10.1038/nphys4092 A family of topologically protected Kondo insulators, termed Möbius Kondo insulators, is predicted. A re-analysis of archival resistivity measurements of Ce3Bi4Pt3 and CeNiSn suggests they may be good candidate members of this class. Quasiparticle interference and strong electron-mode coupling in the quasi-one-dimensional bands of Sr2RuO4   pp799 - 805 Zhenyu Wang, Daniel Walkup, Philip Derry, Thomas Scaffidi, Melinda Rak et al. doi:10.1038/nphys4107 The normal state of the ruthenate Sr2RuO4 is not that of a conventional metal but one with enhanced correlation effects, which may help to elucidate the origin of the unconventional superconductivity observed in this material. Mottness at finite doping and charge instabilities in cuprates   pp806 - 811 S. Peli, S. Dal Conte, R. Comin, N. Nembrini, A. Ronchi et al. doi:10.1038/nphys4112 The electron dynamics of single-layer Bi2Sr2–xLaxCuO6+δ is studied as a function of doping, revealing the evolution of charge-transfer excitations from incoherent and localized (as in a Mott insulator) to coherent and delocalized (as in a conventional metal).

Studies of BaTiO3 thin films now reveal a close coupling between the ferroelectric and the surface electrochemical states — a notion important for future applications of ferroelectric nanomaterials. Measure for Measure Top The invention of dimension   p820 Steven T. Bramwell doi:10.1038/nphys4229 Assigning dimensions to physical quantities is not just for practicality. Steven T. Bramwell reflects on the deeper physical connotations of it all. Top Natureevents is a fully searchable, multi-disciplinary database designed to maximise exposure for events organisers.
