This Focus surveys the field of magnon spintronics, which harnesses quantized spin waves – magnons – as the carriers of spin currents. Editorial Top Focus on Magnon spintronics The next wave   p437 doi:10.1038/nphys3367 Spin waves look poised to make a splash in data processing. Commentary Top Focus on Magnon spintronics Reconfigurable magnonics heats up   pp438 - 441 Dirk Grundler doi:10.1038/nphys3349 Coupling electromagnetic waves to mechanical waves has led to a remarkable miniaturization of wireless communication technologies. Now, spin waves could provide us with technologies that are small and reprogrammable. Thesis Top SOC revisited   p442 Mark Buchanan doi:10.1038/nphys3354 Research Highlights Top Hit and flip | Know the ropes | Cell swell | Balancing act | When we were young News and Views Top Spin-orbit physics: Kitaev matter   pp444 - 445 Philipp Gegenwart and Simon Trebst doi:10.1038/nphys3346 Spin-orbit entangled local moments in the iridate material Na2IrO3 are subject to strong exchange frustration, driving the system towards a spin-liquid phase with emergent fractional excitations. See also: Letter by Hwan Chun et al. | Supernovae: Searching for companions   pp445 - 446 Anthony L. Piro doi:10.1038/nphys3353 New observations suggest that two highly debated mechanisms for type Ia supernovae — our standard distance 'candles' for astrophysical objects — may both be correct. Non-equilibrium condensation: State of the game   pp446 - 448 Sebastian Diehl doi:10.1038/nphys3351 Condensation usually describes a winner-takes-all phenomenon, in which a single state is macroscopically occupied. Game theory now reveals a mechanism for selecting an entire network of condensate states in a driven quantum system. Excitons: Molecules in flatland   pp448 - 449 Wang Yao doi:10.1038/nphys3350 Forming molecules from atoms is commonplace in dense atomic gases. But it now seems that some two-dimensional materials provide a suitable environment for creating complex molecular states from the hydrogen-like electron-hole pairs that form in semiconductors. See also: Letter by You et al. | Ten years of Nature Physics: Bound to be universal?   pp449 - 451 Cheng Chin and Yujun Wang doi:10.1038/nphys3352 Three papers published in Nature Physics in 2009 revealed the intriguing three- and four-body bound states arising from the predictions by Vitaly Efimov nearly half a century ago. But some of these findings continue to puzzle the few-body physics community.

V. Chumak, V. I. Vasyuchka, A. A. Serga and B. Hillebrands doi:10.1038/nphys3347 Magnons provide a route for information-processing technologies that are free from charge-related dissipations. Advances in the manipulation of magnons, and the conversion to charge currents, bring magnon-based computing closer to realization. Letters Top Direct evidence for dominant bond-directional interactions in a honeycomb lattice iridate Na2IrO3   pp462 - 466 Sae Hwan Chun, Jong-Woo Kim, Jungho Kim, H. Zheng, Constantinos C. Stoumpos et al. doi:10.1038/nphys3322 Honeycomb iridates have been proposed as experimental realizations of the Kitaev model. An X-ray scattering study presents evidence for bond-directional interactions in Na2IrO3, a key requirement to make the connection with Kitaev physics possible. See also: News and Views by Gegenwart & Trebst | Rotational state-changing cold collisions of hydroxyl ions with helium   pp467 - 470 Daniel Hauser, Seunghyun Lee, Fabio Carelli, Steffen Spieler, Olga Lakhmanskaya et al. doi:10.1038/nphys3326 Understanding low-temperature molecular collisions is challenging, but using non-resonant photodetachment makes it possible to study the state-resolved dynamics of the inelastic collisions between hydroxyl ions and cold helium buffer gas. Enhanced electron coherence in atomically thin Nb3SiTe6   pp471 - 476 J. Hu, X. Liu, C. L. Yue, J. Y. Liu, H. W. Zhu et al. doi:10.1038/nphys3321 The effect of electron-phonon interactions on transport properties of 2D materials is unclear. Transport measurements on atomically thin Nb3SiTe6 crystals now show that reduced dimensionality results in the suppression of electron-phonon coupling. Observation of biexcitons in monolayer WSe2   pp477 - 481 Yumeng You, Xiao-Xiao Zhang, Timothy C. Berkelbach, Mark S. Hybertsen, David R. Reichman et al. doi:10.1038/nphys3324 Strong many-body Coulomb interactions allow for bound two- and three-body excitonic states to form in monolayer transition metal dichalcogenides, but it is now shown that such interactions are strong enough to create four-body biexcitonic states. See also: News and Views by Yao | Bandgap opening in few-layered monoclinic MoTe2   pp482 - 486 Dong Hoon Keum, Suyeon Cho, Jung Ho Kim, Duk-Hyun Choe, Ha-Jun Sung et al. doi:10.1038/nphys3314 Monoclinic transition metal dichalcogenides offer the possibility of topological quantum devices, but they are difficult to realize. One route may be through switching from the common hexagonal phase, for which a method is now shown. Focus on Magnon spintronics Optically reconfigurable magnetic materials   pp487 - 491 Marc Vogel, Andrii V. Chumak, Erik H. Waller, Thomas Langner, Vitaliy I. Vasyuchka et al. doi:10.1038/nphys3325 The periodic modulation of the magnetic properties of magnonic crystals controls the flow of spin waves. An optical method is now shown that can produce such modulations by heating, which can be reprogrammed during operation. Magnetic jam in the corona of the Sun   pp492 - 495 F. Chen, H. Peter, S. Bingert and M. C. M. Cheung doi:10.1038/nphys3315 Simulations help reveal the complex relationship between the changing structure of the magnetic field lines and the plasma in the corona of the Sun, which is one hundred times hotter than the surface itself. Articles Top Role of transparency of platinum-ferromagnet interfaces in determining the intrinsic magnitude of the spin Hall effect   pp496 - 502 Weifeng Zhang, Wei Han, Xin Jiang, See-Hun Yang and Stuart S. P. Parkin doi:10.1038/nphys3304 The spin Hall effect induces spin currents in nonmagnetic layers, which can control the magnetization of neighbouring ferromagnets. The transparency of the interface is shown to strongly influence the efficiency of such manipulation. Interpreting attoclock measurements of tunnelling times   pp503 - 508 Lisa Torlina, Felipe Morales, Jivesh Kaushal, Igor Ivanov, Anatoli Kheifets et al. doi:10.1038/nphys3340 Understanding the physical mechanisms of photon-atom interactions on ultrafast timescales is challenging, but a new theoretical framework enables the interpretation of attoclock experiments measuring tunnelling times in hydrogen. Energy flow in quantum critical systems far from equilibrium   pp509 - 514 M. J. Bhaseen, Benjamin Doyon, Andrew Lucas and Koenraad Schalm doi:10.1038/nphys3320 Gauge/gravity duality is normally reserved for the study of black holes, but it can be applied to the study of out-of-equilibrium quantum systems in arbitrary dimension.

C. De Groot, I. Bloch et al. doi:10.1038/nphys3338 Futures Top Undervoidable   p516 Ian Watson doi:10.1038/nphys3358 The price of exploration.
