A Nobel opportunity for interdisciplinarity pp1075 - 1078 Michael Szell, Yifang Ma & Roberta Sinatra doi:10.1038/s41567-018-0314-6 Despite the growing interdisciplinarity of research, the Nobel prize consolidates the traditional disciplinary categorization of science. There is, in fact, an opportunity for the most revered scientific reward to mirror the current research landscape. |

|
Reconstructing the topology of optical polarization knots pp1079 - 1082 Hugo Larocque, Danica Sugic, Dominic Mortimer, Alexander J. Taylor, Robert Fickler et al. doi:10.1038/s41567-018-0229-2 Knotted lines representing torus knot and figure-eight knot are produced in the polarization profile of optical beams, leading to a topological characterization of the structure of the polarization field. |

Direct entropy measurement in a mesoscopic quantum system pp1083 - 1086 Nikolaus Hartman, Christian Olsen, Silvia Lüscher, Mohammad Samani, Saeed Fallahi et al. doi:10.1038/s41567-018-0250-5 The entropy of a few-electron quantum system is measured for the first time by tracking the movement of charge in and out of the system. This could allow the unambiguous detection of Majorana fermions in solid state devices. |
|
|
|
Phase-controlled coherent dynamics of a single spin under closed-contour interaction pp1087 - 1091 Arne Barfuss, Johannes Kölbl, Lucas Thiel, Jean Teissier, Mark Kasperczyk et al. doi:10.1038/s41567-018-0231-8 Coherent driving of all transitions of a three-level system generates a closed-contour interaction, which is here shown to create efficient manipulation methods for electronic spins in nitrogen–vacancy centres in diamond. |

|
Biexcitonic optical Stark effects in monolayer molybdenum diselenide pp1092 - 1096 Chaw-Keong Yong, Jason Horng, Yuxia Shen, Hui Cai, Alex Wang et al. doi:10.1038/s41567-018-0216-7 Light–matter interactions in monolayer MoSe2 can be dramatically modified by the interactions between the excitonic states, leading to a rich set of light-driven coherent phenomena. |

|
|
Complex magnetic order in nickelate slabs pp1097 - 1102 M. Hepting, R. J. Green, Z. Zhong, M. Bluschke, Y. E. Suyolcu et al. doi:10.1038/s41567-018-0218-5 Surprising phenomena are known to occur when magnetic systems are confined to low-dimensional geometries. A resonant X-ray scattering study of NdNiO3 slabs reveals a crossover between different magnetic ground states as a function of thickness. |

|
Time-resolved collapse and revival of the Kondo state near a quantum phase transition pp1103 - 1107 C. Wetli, S. Pal, J. Kroha, K. Kliemt, C. Krellner et al. doi:10.1038/s41567-018-0228-3 Using terahertz pulses, the quasiparticle dynamics of the heavy-fermion compound CeCu6−xAu are investigated in the vicinity of its quantum critical point. |

Transport and dispersion across wiggling nanopores pp1108 - 1113 Sophie Marbach, David S. Dean & Lydéric Bocquet doi:10.1038/s41567-018-0239-0 Fluid transport at the nanoscale is important for understanding a range of phenomena in biological and physical systems. A theory accounting for transport through fluctuating channels is presented, providing a framework for designing active membranes. |

Targeted assembly and synchronization of self-spinning microgears pp1114 - 1118 Antoine Aubret, Mena Youssef, Stefano Sacanna & Jérémie Palacci doi:10.1038/s41567-018-0227-4 Active colloidal particles are shown to be capable of aggregating into stable spinning clusters that constitute self-powered microgears. The demonstration reveals a new design principle for micromachinery using dissipative building blocks. |

Giant anomalous Nernst effect and quantum-critical scaling in a ferromagnetic semimetal pp1119 - 1124 Akito Sakai, Yo Pierre Mizuta, Agustinus Agung Nugroho, Rombang Sihombing, Takashi Koretsune et al. doi:10.1038/s41567-018-0225-6 A magnetic field and temperature gradient produce a large electric potential in a ferromagnet, indicating the possible presence of Weyl points. The specific structure of Weyl points gives the electrons quantum-critical properties. |

Giant anomalous Hall effect in a ferromagnetic kagome-lattice semimetal pp1125 - 1131 Enke Liu, Yan Sun, Nitesh Kumar, Lukas Muechler, Aili Sun et al. doi:10.1038/s41567-018-0234-5 Electrical transport measurements reveal that Co3Sn2S2 is probably a magnetic Weyl semimetal, and hosts the highest simultaneous anomalous Hall conductivity and anomalous Hall angle. This is driven by the strong Berry curvature near the Weyl points. |

Precision spectroscopy of helium in a magic wavelength optical dipole trap pp1132 - 1137 R. J. Rengelink, Y. van der Werf, R. P. M. J. W. Notermans, R. Jannin, K. S. E. Eikema et al. doi:10.1038/s41567-018-0242-5 A highly precise measurement of an optical transition in the helium atom has been obtained using state-of-the-art techniques. The result provides a stringent test of QED theory at low energy levels with tools of atomic physics. |

Superconducting, insulating and anomalous metallic regimes in a gated two-dimensional semiconductor–superconductor array pp1138 - 1144 C. G. L. Bøttcher, F. Nichele, M. Kjaergaard, H. J. Suominen, J. Shabani et al. doi:10.1038/s41567-018-0259-9 The phase transition between a superconductor and insulator is examined in a new type of heterostructure. A metallic regime is found, which disappears in a magnetic field, giving fresh insight to a paradigmatic quantum phase transition. |
