Subscribe   Facebook   RSS   Recommend to library   Twitter   Editorial Top The Universe itself   p517 doi:10.1038/nphys3405 The general theory of relativity, tested time and time again, is a cornerstone of modern physics — but marrying it with quantum mechanics remains a major challenge. Commentary Top The truth phalanx   pp518 - 519 Milena Wazeck doi:10.1038/nphys3317 The history of the fierce opposition met by Einstein's theory of relativity in the 1920s teaches us that public controversies about science are not necessarily settled by sound scientific reasoning. Thesis Top Anthropic attitudes   p520 Mark Buchanan doi:10.1038/nphys3388 Books and Arts Top Relativity related   pp521 - 522 Bart Verberck reviews Einstein's Masterwork: 1915 and the General Theory of Relativity by John Gribbin doi:10.1038/nphys3392 Exhibition: Patterns in the dark   p522 doi:10.1038/nphys3391 Research Highlights Top Supernovae: Lone star states | Soft matter: Droplet duster | Topological superconductivity: Edging closer | Quantum gravity: Draw the line | X-ray imaging: Miniature meltdown News and Views Top Quantum Hamiltonian complexity: Worth the wait   pp524 - 525 Frank Verstraete doi:10.1038/nphys3381 Quantum many-body systems are often so complex as to be intractable. An algorithm that finds the ground state of any one-dimensional quantum system has now been devised, proving that the many-body problem is tractable for quantum spin chains.

Ultracold gases: At the edge of mobility   pp525 - 526 Laurent Sanchez-Palencia doi:10.1038/nphys3379 The Anderson transition point between localization and diffusion — the mobility edge — has now been directly measured in an ultracold-atom experiment. See also: Article by Semeghini et al. Superconducting transistors: A boost for quantum computing   pp527 - 528 Francesco Giazotto doi:10.1038/nphys3387 A niobium titanite nitride-based superconducting nanodevice — a Cooper-pair transistor — has a remarkably long parity lifetime, exceeding one minute close to absolute zero. See also: Letter by van Woerkom et al. Ten years of Nature Physics: It's not always who you know   pp528 - 529 Romualdo Pastor-Satorras doi:10.1038/nphys3380 Certain nodes are influential in spreading information — or infection — across a network. But these nodes need not be those with the most connections, and topology can play a key role, as a 2010 paper in Nature Physics established. High-harmonic generation: To the extreme   pp529 - 530 Giulio Vampa and David M. Villeneuve doi:10.1038/nphys3386 High-harmonic spectroscopy is a powerful tool for probing the electronic structure of atoms and molecules in gases. Experiments now show that similar emission from solids has a different origin. Physics JOBS of the week Postdoctoral Researcher in Medical Physics Hokkaido University Postdoctoral Research Physicist – Ultrasound Physics Institute of Cancer Research (ICR) Faculty Position in Atomic, Molecular and Optical (AMO) Physics Ecole Polytechnique Fédérale de Lausanne (EPFL) Professorship (W3) of Theoretical Physics (Succession of Prof. Blumen) Universität Freiburg More Science jobs from Physics EVENT International Symposium on Physics and Applications of Laser Dynamics (IS-PALD) 4th Nov - 6th Nov 2015 Metz, France More science events from Review Top Anomalous critical and supercritical phenomena in explosive percolation   pp531 - 538 Raissa M. D’Souza and Jan Nagler doi:10.1038/nphys3378 The transition to widespread connectivity in networks is aptly described by concepts borrowed from percolation theory. Attempts to delay the transition with small interventions lead to explosive percolation, with drastic consequences for the system. Letters Top Wheeler's delayed-choice gedanken experiment with a single atom   pp539 - 542 A. G. Manning, R. I. Khakimov, R. G. Dall and A. G. Truscott doi:10.1038/nphys3343 In a delayed-choice experiment the decision to measure the particle or wave nature comes after the photon enters the interferometer. An atomic version of the experiment provides the same outcome despite the mass and internal structure of the atoms. Observation of a robust zero-energy bound state in iron-based superconductor Fe(Te,Se)   pp543 - 546 J-X. Yin, Zheng Wu, J-H. Wang, Z-Y. Ye, Jing Gong et al. doi:10.1038/nphys3371 The symmetry of Cooper pairs in iron-based superconductors is an issue under continued investigation. A scanning tunnelling study of Fe(Te,Se) reveals a robust zero-energy bound state, providing evidence for a non-trivial pairing symmetry. One minute parity lifetime of a NbTiN Cooper-pair transistor   pp547 - 550 David J. van Woerkom, Attila Geresdi and Leo P. Kouwenhoven doi:10.1038/nphys3342 One minute parity lifetimes are reported in a superconducting transistor made of niobium titanite nitride coupled to aluminium contacts even in the presence of small magnetic fields, enabling the braiding of Majorana bound states.

However, optical spectra suggest these different sources may be more similar than once thought. Articles Top Measurement of the mobility edge for 3D Anderson localization   pp554 - 559 G. Semeghini, M. Landini, P. Castilho, S. Roy, G. Spagnolli et al. doi:10.1038/nphys3339 The mobility edge characterizes the transition from localization to diffusion. This key parameter in Anderson localization was measured for a system of ultracold atoms in a tunable disordered potential created by laser speckles. See also: News and Views by Sanchez-Palencia Nonlocal adiabatic response of a localized system to local manipulations   pp560 - 565 Vedika Khemani, Rahul Nandkishore and S. L. Sondhi doi:10.1038/nphys3344 Anderson localization has recently attracted renewed interest in strongly correlated quantum systems. Now, local adiabatic manipulations are shown to lead to a nonlocal response, with implications for quantum control in disordered environments. A polynomial time algorithm for the ground state of one-dimensional gapped local Hamiltonians   pp566 - 569 Zeph Landau, Umesh Vazirani and Thomas Vidick doi:10.1038/nphys3345 An algorithm that provably finds the ground state of any one-dimensional quantum system is presented, providing a promising alternative to the widely used, but heuristic, density matrix renormalization group approach.

Thermal spin-transfer torque driven by the spin-dependent Seebeck effect in metallic spin-valves   pp576 - 581 Gyung-Min Choi, Chul-Hyun Moon, Byoung-Chul Min, Kyung-Jin Lee and David G. Cahill doi:10.1038/nphys3355 The spin-dependent Seebeck effect converts thermal gradients into spin currents. It is now shown that this effect can be used to drive spin-transfer torques on picosecond timescales using the heat currents created by ultrafast pulses of laser light. Direct measurement of the exciton binding energy and effective masses for charge carriers in organic-inorganic tri-halide perovskites   pp582 - 587 Atsuhiko Miyata, Anatolie Mitioglu, Paulina Plochocka, Oliver Portugall, Jacob Tse-Wei Wang et al. doi:10.1038/nphys3357 Direct measurement of the exciton binding energy shows that the impressive performance of perovskite solar cells arises from the spontaneous generation of free electrons and holes after light absorption. Synchronous universal droplet logic and control   pp588 - 596 Georgios Katsikis, James S. Cybulski and Manu Prakash doi:10.1038/nphys3341 A computer based on droplets moving in microfluidic channels requires synchronous manipulation of the droplets. Such synchronous logic is now shown for a system of ferrofluid droplets, with a rotating magnetic field providing the computer clock rate. Percolation in real interdependent networks   pp597 - 602 Filippo Radicchi doi:10.1038/nphys3374 Our understanding of how catastrophe propagates in multi-layered networks relies on theories that apply only to infinite systems. Reducing the interconnected networks to a set of decoupled graphs provides a route to probing finite sizes. Futures Top Like buses   p604 Martin Hayes doi:10.1038/nphys3407 A voyage into the unknown.
