Representation of the short - range interactions in liquid helium via modified hard sphere potentials
نویسنده
چکیده
In this paper we propose five different modifications of the hard sphere potential for the modeling a short-range repulsion and the calculation of thermodynamic and transport properties of liquid 4He. We calculate the potential energy, the total energy, and the sound velocity at T = 0 K. It is shown that three of the proposed potentials give a satisfactory description of these properties.

Wavelength and polarization variations of InAs/GaAs quantum dots emission at liquid Helium temperature via microphotoluminescence spectroscopy
In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

In previous work, one of us calculated the Solvation force of hard ellipsoid fluid with hard Gaussian overlap potential using hard needle wall interaction and non-linear equation proposed by Grimson- Rickyazen. In present work, using density functional theory and extended restricted orientation model, the solvation force of hard ellipsoid fluid in presence of more realistic rod- sphere and rod-...
متن کاملNon - additive interactions in liquid helium solvent effects
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 o...
متن کاملSelf-Consistent Ornstein-Zernike Approximation (SCOZA) and exact second virial coefficients and their relationship with critical temperature for colloidal or protein suspensions with short-ranged attractive interactions.
We focus on the second virial coefficient B2 of fluids with molecules interacting through hard-sphere potentials plus very short-ranged attractions, namely, with a range of attraction smaller than half hard-sphere diameter. This kind of interactions is found in colloidal or protein suspensions, while the interest in B2 stems from the relation between this quantity and some other properties of t...
