But for Brazil's science communities, the decisions made by the new government could leave scars much deeper than the semi-final defeat. Thesis Top Sizing up bacteria   p788 Mark Buchanan doi:10.1038/nphys3149 Books and Arts Top Exhibition: Grand act   pp789 - 790 Bart Verberck doi:10.1038/nphys3148 Exhibition: Sky's the limit   p790 May Chiao doi:10.1038/nphys3151 Research Highlights Top Nobel Prize 2014: Akasaki, Amano & Nakamura | Novel observations | Hot and bothered | Most wanted | Smart photons | Long live the proton News and Views Top Ultracold atoms: A black-hole laser   pp793 - 794 Giovanni Modugno doi:10.1038/nphys3141 Astrophysical observations of Hawking radiation may be out of reach, but evidence for the self-amplification of Hawking radiation has now been observed in a sonic analogue of a black hole. See also: Article by Steinhauer Quantum control: Engineering a revolution   pp794 - 795 William D. Oliver doi:10.1038/nphys3144 Rapidly changing noise impedes high-fidelity quantum control. An engineering framework for predicting and mitigating such dynamics has now been validated, revealing physical insights into the time evolution of quantum states. See also: Letter by Soare et al. Polaritons: Hungry cavities   pp796 - 797 Cristiano Ciuti doi:10.1038/nphys3136 A microcavity device operating in the strong light-matter interaction regime can produce coherent perfect absorption of photons — providing a viable system for the perfect feeding of polaritons. See also: Letter by Zanotto et al. Nuclear physics: The long way   p797 Iulia Georgescu doi:10.1038/nphys3154 Spintronics: A lucky break   pp798 - 799 John Schaibley and Xiaodong Xu doi:10.1038/nphys3138 The ability to harness spin polarization is critical for many semiconductor spin devices. It now seems that spin-orbit coupling with locally broken symmetry can enable a giant spin polarization in a semiconductor that is otherwise inversion symmetric. See also: Letter by Riley et al. Plasmonic lasers: On the fast track   pp799 - 800 Mark Stockman doi:10.1038/nphys3127 Plasmons offer the tantalizing prospect of accelerated light-matter interactions. Accelerated dynamics has now been observed in a hybrid plasmonic laser or spaser, capable of producing pulses on ultrafast timescales. See also: Article by Sidiropoulos et al. Molecular spectroscopy: Forbidden vibrations   pp800 - 801 Jeroen C. J. Koelemeij doi:10.1038/nphys3113 Laser control of atomic ions through dipole-forbidden transitions has provided a way of probing quantum mechanics. These transitions have now been observed in molecular ions, opening the door to a new generation of spectroscopy experiments. See also: Letter by Germann et al.

Various aspects of the physics of exciton-polariton condensates are now reviewed. Letters Top Imaging the two-component nature of Dirac-Landau levels in the topological surface state of Bi2Se3   pp815 - 819 Ying-Shuang Fu, M. Kawamura, K. Igarashi, H. Takagi, T. Hanaguri et al. doi:10.1038/nphys3084 The electrons associated with the conducting surface states of topological insulators are described by a two-component wavefunction. Experiments on Bi2Se3 now show that the structure of Landau levels reflects this two-component nature. Observation of electric-dipole-forbidden infrared transitions in cold molecular ions   pp820 - 824 Matthias Germann, Xin Tong and Stefan Willitsch doi:10.1038/nphys3085 Dipole-forbidden vibrational transitions in molecular ions are very weak and difficult to characterize. The sympathetic cooling provided by a Coulomb crystal is shown to allow interrogation times long enough to observe them. See also: News and Views by Koelemeij Experimental noise filtering by quantum control   pp825 - 829 A. Soare, H. Ball, D. Hayes, J. Sastrawan, M. C. Jarratt et al. doi:10.1038/nphys3115 Quantum technologies are extremely sensitive to environmental disturbance. Control techniques inspired by classical systems engineering allow selective filtering of the noise spectrum, suppressing time-varying noise over defined frequency bands. See also: News and Views by Oliver Perfect energy-feeding into strongly coupled systems and interferometric control of polariton absorption   pp830 - 834 Simone Zanotto, Francesco P. Mezzapesa, Federica Bianco, Giorgio Biasiol, Lorenzo Baldacci et al. doi:10.1038/nphys3106 The absorption properties of a resonator can be tuned by varying the phase between incoming coherent light beams. Such control is now shown under strong coupling conditions, allowing all incoming energy to be converted into polaritons. See also: News and Views by Ciuti Direct observation of spin-polarized bulk bands in an inversion-symmetric semiconductor   pp835 - 839 J. M. Riley, F. Mazzola, M. Dendzik, M. Michiardi, T. Takayama et al. doi:10.1038/nphys3105 The coupling between spin, valley and layer degrees of freedom in transition-metal dichalcogenides is shown to give rise to spin-polarized electron states, providing opportunities to create and manipulate spin and valley polarizations in bulk solids. See also: News and Views by Schaibley & Xu Degenerate Fermi and non-Fermi liquids near a quantum critical phase transition   pp840 - 844 S. Kambe, H. Sakai, Y. Tokunaga, G. Lapertot, T. D. Matsuda et al. doi:10.1038/nphys3101 Nuclear magnetic resonance measurements reveal two separate relaxation channels—one associated with a Fermi liquid state and the other with a non-Fermi liquid state—coexisting near a quantum phase transition in YbRh2Si2. Spin dynamics and orbital-antiphase pairing symmetry in iron-based superconductors   pp845 - 850 Z. P. Yin, K. Haule and G. Kotliar doi:10.1038/nphys3116 The pairing symmetry of iron pnictide superconductors has been hotly debated. First-principles simulations suggest low-energy spin excitations play a central role in raising the superconducting transition temperature of such materials. Enhancement of long-range correlations in a 2D vortex lattice by an incommensurate 1D disorder potential   pp851 - 856 I. Guillamón, R. Córdoba, J. Sesé, J. M. De Teresa, M. R. Ibarra et al. doi:10.1038/nphys3132 Randomness can disorder a two-dimensional vortex lattice and lead to enhanced long-range correlations. The resulting order-disorder transition occurs in two steps, with critical exponents exceeding predictions. Articles Top Pseudospin-driven spin relaxation mechanism in graphene   pp857 - 863 Dinh Van Tuan, Frank Ortmann, David Soriano, Sergio O. Valenzuela and Stephan Roche doi:10.1038/nphys3083 Spin relaxation in graphene is much faster than theoretically expected. Now, a scenario based on a mixing of spin and pseudospin degrees of freedom and defect-induced spatial spin-orbit coupling variations predicts longer spin relaxation times. Observation of self-amplifying Hawking radiation in an analogue black-hole laser   pp864 - 869 Jeff Steinhauer doi:10.1038/nphys3104 Quantum effects allow black holes to radiate—offering a glimpse of how quantum field theory and general relativity might fit together. Hawking radiation has now been observed in a black hole analogue, with evidence that it can self-amplify.

H. Sidiropoulos, Robert Röder, Sebastian Geburt, Ortwin Hess, Stefan A. Maier et al. doi:10.1038/nphys3103 Electron scattering limits the optical excitations produced by metal-based lasers to femtosecond timescales. But sub-picosecond pulsing can be achieved in a plasmonic nanowire laser by operating near the surface plasmon frequency. See also: News and Views by Stockman Exotic circuit elements from zero-modes in hybrid superconductor-quantum-Hall systems   pp877 - 882 David J. Clarke, Jason Alicea and Kirill Shtengel doi:10.1038/nphys3114 A superconductor placed near a quantum Hall edge can show emergent excitations with a range of exotic features. For instance, such heterostructures are predicted to exhibit non-local signatures that are direct extensions of 'Andreev reflection'. Asymmetry of collective excitations in electron- and hole-doped cuprate superconductors   pp883 - 889 W. S. Lee, J. J. Lee, E. A. Nowadnick, S. Gerber, W. Tabis et al. doi:10.1038/nphys3117 Cuprate superconductors are created by adding electrons or holes to a 'parent' compound. They have dissimilar phase diagrams and the asymmetry is further highlighted by unexpected collective modes measured using resonant inelastic X-ray scattering.
