INTERPLAY BETWEEN STRUCTURAL AND ELECTRONIC PROPERTIES OF CARBON NANOTUBES
... In Fig. 1 we present results for the charge distribution and the total potential of a hollow single-wall nanotube, a thin nanowire, a tube filled by a nanowire, and a double-wall nanotube. In these calculations, the C4+ ion charges in each nanotube wall have been smeared out into infinitely thin cylin ...

Entanglement and its Role in Shor`s Algorithm

The entanglement between the registers builds up to a maximum during the first two U(j) gates, then stays constant unt ...

The single most resposible factor for this impression is not the lack of information or theoretical concepts but rather the absence of clear and correct ideas about the relations betwe ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
