Quantum second virial coefficient paradox

Physics Letters A, 1986
Abstract The quantum second virial coefficient vanishes when we apply directly Moller operators. We analyze such a paradox, giving an answer: Usual scattering formulas fail in some cases.

Second virial coefficient for directed manifolds

Physical Review A, 1991
The second virial coefficient for a D-dimensional polymerized manifold with only mutual repulsive interaction for the same internal D coordinate has been calculated using the perturbative renormalization-group method. This can be carried out to all orders of the perturbative expansion for this model.

Second virial coefficients of dipolar hard spheres

Journal of Physics: Condensed Matter, 2010
An asymptotic formula is reported for the second virial coefficient B(2) of a dipolar hard-sphere (DHS) fluid, in zero external field, for strongly coupled dipolar interactions. This simple formula, together with the one for the weak-coupling B(2), provides an accurate prediction of the second virial coefficient for a wide range of dipole moments ...

Second virial coefficient at low temperatures

Physica A: Statistical Mechanics and its Applications, 1977
Abstract The S-matrix-pole-representation of the second virial coefficient for short range potentials is discussed. The method is especially useful at low temperatures.

The Second Virial Coefficient near Absolute Zero

Proceedings of the Physical Society. Section A, 1952
By the solution of Bloch's equation for the density matrix, a development is obtained suitable for the exact evaluation of the second virial coefficient near absolute zero Assuming a molecular interaction of the Lennard-Jones type, it is shown that the virial coefficient for helium is -{½(πβ)3/2+31 15πβ+O(1)}A3, πβ=38 04/T General formulae are given ...

GENERAL FORMULA FOR THE SECOND VIRIAL COEFFICIENT

Canadian Journal of Physics, 1961
A simple derivation is given of the quantum mechanical expression for the second virial coefficient in terms of the scattering phase shifts. The derivation does not require the introduction of a quantization volume and is based on the identity R(z)−R0(z) = R0(z)H1R(z), where R0(z) and R(z) are the resolvent operators corresponding to the unperturbed ...
