How does your institution compare?    Editorial Top Still irresistible   p329 doi:10.1038/nphys2972 Half a century on, the Kondo effect continues to inspire. Thesis Top Make the connection   p331 Mark Buchanan doi:10.1038/nphys2963 Research Highlights Top Easy as pi | Up against the wall | Dynamical breaking | Stellar flashback | Motion picture News and Views Top Spin-orbit interactions: Hide and seek   pp333 - 334 Bart Partoens doi:10.1038/nphys2956 It is commonly believed that solids with spatial inversion symmetry do not display spin-orbit effects. However, first-principles calculations now reveal unexpected spin structure for centrosymmetric crystals. See also: Article by Zhang et al. Holographic duality: Back to reality?   pp334 - 335 Joe Bhaseen doi:10.1038/nphys2938 Holographic dualities discovered in string theory may provide methods for extracting the real-time response of quantum systems from numerical simulations performed in imaginary time. See also: Article by Witczak-Krempa et al. Sports science: In pursuit of power   p335 Bart Verberck doi:10.1038/nphys2965 Nonlinear optics: Asymmetry from symmetry   pp336 - 337 Chong Yidong doi:10.1038/nphys2941 An unusual form of symmetry breaking in coupled microresonators with balanced optical gain and loss is now exploited to realize a novel type of optical isolator. See also: Article by Peng et al. Spintronics: Mux ado about magnons   p337 Luke Fleet doi:10.1038/nphys2966 Nuclear physics: Track it to the limit   pp338 - 339 Philip Walker doi:10.1038/nphys2962 Powerful γ-ray detectors are revealing fresh details about the interior of the nucleus, focusing initially on cases where there is a large excess of neutrons and edging towards the neutron drip-line limit. Paramagnons: The long and the short of it   pp339 - 340 Oleg P. Sushkov doi:10.1038/nphys2955 Paramagnons with unexpectedly long lifetimes are observed in the paramagnetic state at temperatures above the antiferromagnetic ordering temperature in TlCuCl3, posing a challenge to theory. See also: Article by Merchant et al. Spin-orbitronics: A new moment for Berry   pp340 - 341 Aurelien Manchon doi:10.1038/nphys2957 The standard description of spin-orbit torques neglects geometric phase effects. But recent experiments suggest that the Berry curvature gives rise to an anti-damping torque in systems with broken inversion symmetry.

Recent theoretical and experimental advances uncover the interplay between real spin and pseudospins in layered transition metal dichalcogenides. Letters Top Fast-cooling synchrotron radiation in a decaying magnetic field and γ-ray burst emission mechanism   pp351 - 356 Z. Lucas Uhm and Bing Zhang doi:10.1038/nphys2932 Gamma-ray bursts are among the most luminous explosions in the cosmos, but the mechanism behind the energetic radiation remains unclear. 'Fast cooling' electrons in a decaying magnetic field may offer an explanation. Effect of the pseudogap on the transition temperature in the cuprates and implications for its origin   pp357 - 360 Vivek Mishra, U. Chatterjee, J. C. Campuzano and M. R. Norman doi:10.1038/nphys2926 An argument by contradiction shows that the pseudogap state in the high-temperature superconducting cuprates is due to the superconducting pairing rather than being an independent or even competing state. Articles Top The dynamics of quantum criticality revealed by quantum Monte Carlo and holography   pp361 - 366 William Witczak-Krempa, Erik S. Sørensen and Subir Sachdev doi:10.1038/nphys2913 Although the concept of a quasiparticle—a particle plus interactions—works very well for some problems, in other cases quasiparticles can be destroyed by quantum fluctuations. Alternative theoretical techniques for handling strong interactions are needed, such as those from string theory. See also: News and Views by Bhaseen Ferroelectric quantum criticality   pp367 - 372 S. E. Rowley, L. J. Spalek, R. P. Smith, M. P. M. Dean, M. Itoh et al. doi:10.1038/nphys2924 Quantum criticality is often found in metallic compounds that are close to being magnetic. What about insulators in which the electric moments are fluctuating? These too can be described by the same framework—over a wider temperature range than in quantum critical metals. Quantum and classical criticality in a dimerized quantum antiferromagnet   pp373 - 379 P. Merchant, B. Normand, K. W. Krämer, M. Boehm, D. F. McMorrow et al. doi:10.1038/nphys2902 The thermal and quantum fluctuations around a quantum critical point can be studied independently by mapping the evolution of the spin dynamics in the critical region of a dimerized quantum magnet using neutron scattering.

The phase coupling between the islands can be controlled by a gate. Quantum phase fluctuations kill the superconductivity and lead to a metallic state, however, at higher magnetic fields superconductivity can return. Hidden spin polarization in inversion-symmetric bulk crystals   pp387 - 393 Xiuwen Zhang, Qihang Liu, Jun-Wei Luo, Arthur J. Freeman and Alex Zunger doi:10.1038/nphys2933 Spin polarization due to spin-orbit coupling requires broken inversion symmetry. Now, calculations show that the effect arises from local site-asymmetry rather than global space-group asymmetry, and that a hitherto overlooked form of spin polarization should also exist in centrosymmetric structures. See also: News and Views by Partoens Parity-time-symmetric whispering-gallery microcavities   pp394 - 398 Bo Peng, Şahin Kaya Özdemir, Fuchuan Lei, Faraz Monifi, Mariagiovanna Gianfreda et al. doi:10.1038/nphys2927 It is now shown that coupled optical microcavities bear all the hallmarks of parity-time symmetry; that is, the system's dynamics are unchanged by both time-reversal and mirror transformations. The resonant nature of microcavities results in unusual effects not seen in previous photonic analogues of parity-time-symmetric systems: for example, light travelling in one direction is resonantly enhanced but there are no resonance peaks going the other way.
