Nanospherical heterolayer in strong electrostatic field

Strong electrostatic interactions in spherical colloidal systems.

We investigate spherical macroions in the strong Coulomb coupling regime within the primitive model in salt-free environment. We first show that the ground state of an isolated colloid is naturally overcharged by simple electrostatic arguments illustrated by the Gillespie rule. We furthermore demonstrate that in the strong Coulomb coupling this mechanism leads to ionized states and thus to long...

Electrostatic Field Invisibility Cloak.

The invisibility cloak has been drawing much attention due to its new concept for manipulating many physical fields, from oscillating wave fields (electromagnetic, acoustic and elastic) to static magnetic fields, dc electric fields, and diffusive fields. Here, an electrostatic field invisibility cloak has been theoretically investigated and experimentally demonstrated to perfectly hide two dime...

The Electrostatic Field Is Conservative

Let's first consider the field of a point charge. dl The work done to move q from a to b:         b a b a l E l F d q d W Since E = E(r) (recall Coulomb's law), W is independent of the path.

Silicon/silicon Dioxide Nanostructure in Electrostatic Field

Paper presents a numerical analysis of quantum states and probability ψψ* function of a Si/SiO2 nanostructure in varying electrostatic field. The position of probability function peak xp is traced and the bias, under which it abandons the structure (emission or discharging bias), is determined. Variations of the ground state energy with the bias is also examined. The Poisson Schrödinger model o...
