Resource—A concentration of naturally occurring solid, liquid, or gaseous material in or on the Earth’s crust in such form and amount that economic extraction of a commodity from the concentration is currently or potentially feasible. Reserve Base—That part of an identified resource that meets ...

4.3 Electrons on the Surface of Thin Liquid Helium Film In the above sections, we have treated electron systems formed on bulk liquid or bulk solid materials. In this subsection, we mention the electron systems formed on very thin helium film. This system is of interest, because the interactio...
We have calculated the contribution of the triple-dipole three-body interactions to the ground-state energy of liquid Heand solid He. The liquid calculation was done by a Monte Carlo method using a variationally determined product wave function, and the solid calculation by evaluating the triple-...

The universe abounds with solid helium in polymorphic forms. Therefore, exploring the allotropes of helium remains vital to our understanding of nature. However, it is challenging to produce, observe and utilize solid helium on the earth because high-pre
helium was first liquefied by Dutch physicist Heike Kamerlingh Onnes by cooling the gas to less than one kelvin.[16] He tried to solidify it by further reducing the temperature but failed because helium does not have a triple point temperature at which the solid, liquid, and gas phases are ...
In view of recent experiments, we also consider overpressurized liquid helium 4 and address the question of the stability of the superfluid phase against the solid.FrédéricCaupinandSébastienBalibarandHumphreyJ.MarisEBSCO_AspPhysica B: Condensed Matter...
Helium confined in various porous media11 does exhibit elastic scattering due to the presence of solid layers strongly adsorbed on the pore boundaries (see Fig. 1b). However, in previously studied pores with large radii that are not yet in the quasi-1D regime, dense liquid layers and a ...
