  • Josephson junctions based on topological insulators are expected to host Majorana bound states which are accompanied by the experimental absence of odd Shapiro steps in current-voltage characteristics. Here, the authors investigate Shapiro steps in a ballistic junction with Bi2Te2.3Se0.7, finding that overheating effects, rather than topological superconductivity, are sufficient to explain the suppression of the first step, challenging conventional interpretations.

  • Quantum condensates may penetrate from one material to another due to the proximity effect. Here, Stolyarov et al. report the spatial evolution of quantum vortices from a superconducting Nb layer to a 50 nanometer thick diffusive metallic Cu-film, which is quite thick away from the interface.

  • Manipulation of individual superconducting vortices remains challenging and has been demonstrated only in a sophisticated way. Here, Veshchunov et al.realize a fast and precise manipulation of individual vortices using a far-field optical method, providing a simple way towards optical control of Josephson transport.

  • Josephson vortices (JVs) play an important role in superconducting quantum devices, but they remain difficult to be observed and manipulated. Here, Dremov et al. report magnetic fingerprint of JVs in magnetic force microscopy experiments, which paves a way to generate and control JVs.

  • Controlling the motion and pinning of vortices is essential for developing superconducting electronics. Here, the authors reveal the vortex pinning nano-network in thin superconducting niobium films by developing a scanning quantum vortex microscopy approach.

  • The textile industry is one of the largest polluters. Here the authors show that polyethylene is a sustainable alternative textile with water wicking and fast-drying performance. The fabrication of polyethylene fabrics is compatible with standard equipment and could be dry-coloured, further reducing water consumption.

  • Doping 2D materials is an effective way to engineer a wide range of properties of interest from catalysis to quantum bits. Here, the authors investigate Br-doped 2H-MoTe2 using electron spin resonance and scanning tunneling spectroscopy, demonstrating that the dopant-orbitals hybridise to the Q-valleys of the conduction band and produce long-lived spin states protected by spin-valley locking.

  • Topological insulators in contact with a superconductor could house unusual physical states such as Majorana fermions. Here, the authors fabricate and report the  electron-transport characteristics of Josephson junctions built using a nanoscale topological insulator, finding evidence for ballistic transport in the surface states of the nanocrystals.

  • Topological insulators with ordered moments of embedded magnetic atoms are viable platforms for quantum electronics, but the practical applications are restricted by the size of their crystals. The authors synthesize a Z2 topological insulator GexMn1-xBi2Te4 in the form of a large crystal with high structural perfection and tunable magnetic and electronic properties.
