In this paper we present experimental data on helium ...
Quantum computation of the properties of helium using two-body and three-body intermolecular potentials: a molecular dynamics study[J] . Elaheh K. Goharshadi,Mohsen Abbaspour,Hamideh Kashani,Mahmood Baherololoom.Theoretical Chemistry Accounts . 2008 (4)...
Helium is the second most abundant chemical element in the universe. For example, hexagonal close-packed metallic helium is expected to dominate the secular cooling process of white dwarf stars1. At low temperatures, helium can become archetypal quantum crystals with exotic physical properties, such ...
In the phase diagram of water, superionic ices with highly mobile protons within the stable oxygen sublattice have been predicted at high pressures. However, the existence of superionic ices and the location of the melting line have been challenging to d
inter atomic pair potential/ A6780 Solid helium and related quantum crystalsThe wrong volume dependence of calculated solid helium ground-state properties is shown to be due, at least partly, to the inadequate choice of the inter-atomic pair potential....
The thermodynamic equation of state plays a key role in calculating the heat transfer coefficient which is a function of thermodynamic and thermophysical properties. An investigation has been performed to study the performance of two- and three-parameter equations of state to calculate the ...
Changing the interaction strength between the nanodroplet and the solid wall, εw-Pt can realize the regulation of the wall from superhydrophobic to superhydrophilic in the range of 0.1–1.0 kcal·mol−1. Gas-solid phase transition surface properties are the same as liquid-solid phase ...
A Modeling Study of Atmospheric Transport and Photochemistry in the Mixed Layer during Anticyclonic Episodes in Europe. Part I: Meteorology and Air Trajectories A climatological study has been carried out of the occurrence and properties of a large number of dry and sunny spells in recent summers ...
A key concept proposed by Landau to explain superfluid liquid helium is the elementary excitation of quantum particles called rotons1–8. The irregular arrangement of atoms in a liquid leads to the aperiodic dispersion of rotons, which played a pivotal r
In other words, the surface system forms an independent two-dimensional superfluid that, at the zero-temperature limit, determines the thermo-mechanical properties of 3He. Confining a fermion gas at a low temperature to a high-purity two-dimensional solid-state system has led to the discovery ...
