The principle of minimal Gibbs energy discussed in Sect.
High-level methods to describe van der Waals interactions are limited
derivation from the van der Waals equation—it depends on the assumption of pairwise potentials, and on there
energy is higher than that of the liquid-gas equilibrium at the same p and T.
dispersion series. The small contributions of the first-order polarization energy and the overlap integrals to the van der Waals potential are examined. Without ...
... free energy tends to the infimum of an effective energy functional la Onsager. ... first order phase transition for liquid crystals in the van der Waals--Kac limit.
The small contributions of the first-order polarization energy and the overlap integrals to the van der Waals potential are examined. Without any adjustable ...
The first order interaction energy between two He atoms is calculated with a large ... uncorrelated result in the region of the van der Waals minimum (R = 5·6 a 0).
In this paper, we will show that although the free energy changes with b, the first order phase transition temperature is the same for different b. If we interpret ...
The second order correction, ∆2E0, to the ground state energy we found is O(|R| −6). We used second order perturbation theory since the first ...
