    Structural characteristics and Multifield Control of 1T-TaS2 CDW

    The crystal structure of 1T-TaS2 is defined by its distinctive layered arrangement, where each layer consists of a central plane of tantalum (Ta) atoms coordinated in an octahedral…

    Tight-binding model for a fault in Bernal graphite

    The structure of an ABC stacking fault is sketched in Fig. 1a, where we also label all the involved SWMcC tight-binding model parameters. In this sketch we use the following color-coding: The…

    Forgotten property of the electron

    The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists at Forschungszentrum Jülich have now discovered that in certain materials it is not…
