    Jahn-Teller distortion driven magnetic polarons in magnetite

    The first known magnetic mineral, magnetite, has unusual properties, which have fascinated mankind for centuries; it undergoes the Verwey transition around 120 K with an abrupt change in structure and electric...

    Asymmetry of collective excitations in electron- and hole-doped cuprate superconductors

    High-temperature superconductivity emerges on do** holes or electrons into antiferromagnetic copper oxides. The large energy scale of magnetic excitations, for example, compared with phonon energies, is thou...

    Optical waves in a gradient negative-index lens of a half-infinite length

    Materials with negative permittivity and permeability can overcome the diffraction limit, thereby making the sub-wavelength imaging possible. In this study, we analyze the effects of gradient index on a half-i...

    Lipid profiling and tolerance to low-temperature stress in Thellungiella salsuginea in comparison with Arabidopsis thaliana

    Changes in membrane lipid composition is a fundamental strategy for plants to resist low-temperature stress. We compared members of 11 membrane glycerolipid classes in Thellungiella salsuginea and its close relat...

    On the properties and stability of thermally evaporated Ge–As–Se thin films

    Thin films of Ge–As–Se chalcogenide glasses have been deposited by thermal evaporation from bulk material and submitted to thermal treatments. The linear refractive index and optical band-gap for as-deposited ...

    Growth and Characterization of PrBa2Cu3O7−x Thin Film Used as Template Layer on SrTiO3 Substrate

    We have grown PrBa2Cu3O7−x (PBCO) thin films on (100) SrTiO3 substrates using pulsed laser deposition (PLD). X-ray diffraction (XRD) studies indicate that the orientation of PBCO films varied with increasing dep...
