    Nbits pinned to an LC defect line. The local nematic director field n(r), indicated by cylindrical bars, rotates by π along closed curves encircling the defect line (black). The director field is colored by its out-of-plane component, nz(r), while xy-planes are colored by the director’s azimuthal orientation nϕ(r) relative to the x axis. The near-field director profile (red) close to the defect line defines the nbit state. The vertical direction may be interpreted as either a spatial or a time dimension.

    Artistic representation showing the twisted layers of tungsten diselenide (top) and molybdenum disulphide (bottom). Following excitation using light, a multitude of optically “dark” excitons form between the layers. These “dark” excitons are electron-hole pairs bound by Coulomb interaction (light and dark spheres connected by field lines), which cannot be directly observed using visible light. One of the most interesting quasiparticles is the “moiré interlayer exciton” – shown in the middle of the image – in which the hole is located in one layer and the electron in the other...

    Using photons and electron spin qubits, researchers demonstrated atomic-scale sensing for use in NMR, and by controlling nuclear spin, creating nuclear qubits with longer coherence times than previously used electron spin qubits.

    By using photons and electron spin qubits to control nuclear spins in a 2D material, researchers at Purdue University have opened a new frontier in quantum science and technology, enabling applications like atomic-scale nuclear magnetic resonance spectroscopy, and to read and write quantum information with nuclear spins in 2D materials.

    As published Monday (Aug...

    A schematic diagram of the method for determining the relationship between the morphology and piezoelectric performance of fiber components

    A research team led by Lim Sang-kyoo, senior researcher of the Division of Energy Technology at DGIST (President Kuk Yang) developed a piezoelectric polymer/ceramic composite fiber with a cross-sectional form that is uniformly controlled to allow the use of energy harvesting technologies that can recycle energy wasted or consumed in everyday life.

    Piezoelectric fiber can produce electrical energy through the piezoelectric effect of the material and drive wearable electronic devices through the movement of the wearer...
