چکیده

The Sinano~lu solvent effect method is here modified to include the exchange-overlap three-body SCF term in addition to the usual triple-dipole term. This is accomplished using an analytical fit which gives a better picture of short range non-additive interactions. The application of this modified model to the dimers (4He)~, (aHe)2 and ~He-4Hc in a liquid ~He environment leads to the lowering of the effective-pair potential energy curve. As a consequence the new terms play a significant role, within the limitations of the method, in the calculation of a bound state of helium dimers immersed in a liquid helium medium,

Solvation of intrinsic positive charge in superfluid helium.

On the basis of electronic structure calculations, the structure of intrinsic positive charge solvated in superfluid helium is identified as triatomic He3(+) ion, which is bound to the surrounding ground state helium atoms through the charge–charge induced dipole interaction in a pairwise additive manner. Bosonic density functional theory calculations show that this ion forms the well-known Atk...

Ring polymer molecular dynamics beyond the linear response regime: Excess electron injection and trapping in liquids.

Ring polymer molecular dynamics (RPMD) is used to directly simulate the injection and relaxation of excess electrons into supercritical helium fluid and ambient liquid water. A method for modulating the initial energy of the excess electron in the RPMD model is presented and used to study both low-energy (cold) and high-energy (hot) electron injections. For cold injection into both solvents, th...

Accurate characteristics of Helium in nano-channels

This article describes an accurate subPico flowmeter bifurcatedin to liquid and gas flowrates less than 1mol/s for both MEMS/NEMS and cryogenic technology applications. The MEMS/NEMS are described as either two Gauges (instrument), or quartz fluctuating forks, even if the liquid or gas flows through an element, as well as cryogenic technology consisting of arrays of e...
