Makris, Mercedeh Khajavikhan, Ziad H. Musslimani, Stefan Rotter et al. doi:10.1038/nphys4323 This Review Article outlines the exploration of the interplay between parity–time symmetry and non-Hermitian physics in optics, plasmonics and optomechanics. Letters   Strongly coupled plasmas obey the fluctuation theorem for entropy production    pp21 - 24 Chun-Shang Wong, J. Goree, Zach Haralson & Bin Liu doi:10.1038/nphys4253 Particles in strongly coupled plasmas behave collectively as in liquids, with additional long-range collisions. Experimental evidence is provided that fluctuation theorems obeyed by liquid are also valid for strongly coupled dusty plasmas. Tunable Klein-like tunnelling of high-temperature superconducting pairs into graphene    pp25 - 29 David Perconte, Fabian A. Cuellar, Constance Moreau-Luchaire, Maelis Piquemal-Banci, Regina Galceran et al. doi:10.1038/nphys4278 Proximity effects enable superconductivity to leak into normal metals. In graphene, a Klein-like tunnelling of superconducting pairs from a high-temperature superconductor allows the proximity effects to be tuned by electric fields. Weyl points and Fermi arcs in a chiral phononic crystal    pp30 - 34 doi:10.1038/nphys4275 Acoustic Weyl points are realized in a three-dimensional chiral phononic crystal that breaks inversion symmetry, with the topological nature of the associate surface states providing robust modes that propagate along only one direction. Self-peeling of impacting droplets    pp35 - 39 Jolet de Ruiter, Dan Soto & Kripa K. Varanasi doi:10.1038/nphys4252 When molten tin droplets impact clean substrates, they either stick or spontaneously detach depending on the substrate temperature. Competition between heat extraction and fluidity controls this behaviour, forgoing the need for surface treatment. A characteristic length scale causes anomalous size effects and boundary programmability in mechanical metamaterials    pp40 - 44 Corentin Coulais, Chris Kettenis & Martin van Hecke doi:10.1038/nphys4269 Mechanism-based metamaterials leverage geometric design to control deformations — a strategy that works well on small scales. But the discovery of a characteristic length scale suggests that the underlying mechanism is distorted for larger systems. Adhesion of Chlamydomonas microalgae to surfaces is switchable by light    pp45 - 49 doi:10.1038/nphys4258 The photoactive properties of microalgae are well documented when it comes to photosynthesis and motility. But it seems their adhesion to surfaces can also be manipulated with light, which may serve to optimize their photoactive functionality. Advertisement npj Materials Degradation is a new open access journal that is now open for submissions. The journal publishes the finest content describing basic and applied research discoveries in the area of corrosion (degradation) and protection of materials.   Sign up for article e-alerts >>>   Articles   Coherence time of over a second in a telecom-compatible quantum memory storage material    pp50 - 54 Miloš Rančić, Morgan P. Hedges, Rose L. Ahlefeldt & Matthew J. Sellars doi:10.1038/nphys4254 A candidate for efficient broadband quantum memory at telecommunication wavelengths is identified. The long coherence time and the efficient optical spin pumping demonstrated in the experiment make it practical for spin-wave storage. Topological materials discovery using electron filling constraints    pp55 - 61 Ru Chen, Hoi Chun Po, Jeffrey B. Neaton & Ashvin Vishwanath doi:10.1038/nphys4277 Electron filling criterion can guide the search for new topological materials with nodal-point or nodal-line Fermi surfaces. Quantum tricritical points in NbFe2    pp62 - 67 Sven Friedemann, Will J. Duncan, Max Hirschberger, Thomas W. Bauer, Robert Küchler et al. doi:10.1038/nphys4242 A thermodynamic study of doped single crystals of NbFe2 reveals the phase diagram of this system as a function of temperature, magnetic field and Nb doping — which includes an unusual quantum tricritical point. Probing electronic binding potentials with attosecond photoelectron wavepackets    pp68 - 73 D. Kiesewetter, R. R. Jones, A. Camper, S. B. Schoun, P. Agostini et al. doi:10.1038/nphys4279 Measurements of the electron wavepackets produced by photoionizing noble gas atoms with an XUV harmonic comb enable the reconstruction of the effective binding potential: a new technique that could be extended to molecules. Laser amplification in excited dielectrics    pp74 - 79 Thomas Winkler, Lasse Haahr-Lillevang, Cristian Sarpe, Bastian Zielinski, Nadine Götte et al. doi:10.1038/nphys4265 Ultrashort high-intensity laser pulses change the properties of dielectrics in different ways. One unexpected outcome is light amplification in an excited dielectric, observed in a two-colour pump–probe experiment. Plasma-based beam combiner for very high fluence and energy    pp80 - 84 R. K. Kirkwood, D. P. Turnbull, T. Chapman, S. C. Wilks, M. D. Rosen et al. doi:10.1038/nphys4271 In a hot, under-dense plasma, eight input beams are combined into a single, well-collimated beam, whose energy is more than triple than that of any incident beam. This shows how nonlinear interactions in plasmas can produce optics beams at much higher intensity than possible in solids. Curvature-induced defect unbinding and dynamics in active nematic toroids    pp85 - 90 Perry W. Ellis, Daniel J. G. Pearce, Ya-Wen Chang, Guillermo Goldsztein, Luca Giomi et al. doi:10.1038/nphys4276 Topological defects in a turbulent active nematic on a toroidal surface are shown to segregate in regions of opposite curvature. Simulations suggest that this behaviour may be controlled — or even suppressed — by tuning the level of activity. Role of graph architecture in controlling dynamical networks with applications to neural systems    pp91 - 98 Jason Z. Kim, Jonathan M. Soffer, Ari E. Kahn, Jean M. Vettel, Fabio Pasqualetti et al. doi:10.1038/nphys4268 The energy needed to control a network is related to the links between driver and non-driver nodes, a linear control theory suggests. Applying the theory to connectome data reveals that diverse dynamics in brain networks incur small energetic cost.
