Scientists at Tomsk Polytechnic University jointly with Russian and international colleagues developed the concept for constructing an "optical vacuum cleaner."  Researchers at Nanjing University in China have now made the first nanopore sensor that works optically and does not require any electrical connections.  An international research team around physicist Wolfgang Lang at the University of Vienna has succeeded in producing the world's densest complex nano arrays for anchoring flux quanta, the fluxons.  Optical properties of materials are based on their chemistry and the inherent subwavelength architecture, although the latter remains to be characterized in depth.  More than 100 years ago, Albert Einstein and Wander Johannes de Haas discovered that when they used a magnetic field to flip the magnetic state of an iron bar dangling from a thread, the bar began to rotate.  Researchers at the Max Born Institute have now generated directed currents at terahertz (THz) frequencies, much higher than the clock rates of current electronics.  Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a simple yet accurate method for finding defects in the latest generation of silicon carbide transistors.  In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion.  Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons.  They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids.  Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons.  Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks.
