Second and third virial coefficients for hydrogen
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1964 Second and third virial coefficients for parahydrogen have been derived from closely spaced PVT data from 24 to 100 °K. They are in good agreement at 100 °K with published data for normal hydrogen. Analytical representations of the combined data from about 20 to 423 °K are presented which may be useful in computation of thermodynamic functions of the ...

An investigation of virial coefficients of gases
, 1969 The most widely used experimental method for studying the forces between pairs of molecules is the determination of the second compressibility virial coefficient, B, defined by: z = Pvm/RT = 1 + B/Vm + C/V2 + . . . For non-polar gases at temperatures well removed from the normal boiling point, it is relatively easy to measure values of B with adequate

Second virial coefficients for He4 and He3 from an accurate relativistic interaction potential [PDF]
, 2020 The second virial coefficient and the second acoustic virial coefficient for helium-4 and helium-3 are computed for a wide range of temperatures (0.5--1000 K) using a highly accurate nonrelativistic interaction potential [M. Przybytek et al., Phys.

On the Second Virial Coefficient [PDF]
The Physics of Fluids, 1959 The second virial coefficient is calculated by a new method which exploits certain results known from formal scattering theory. In particular it is shown that the essential quantity may be expressed as the determinant of the S matrix at a given energy. The present approach suggests several approximation techniques and also seems applicable to many-body

THE FOURTH VIRIAL COEFFICIENT OF ANYONS [PDF]
International Journal of Modern Physics A, 1998 We have computed by a Monte Carlo method the fourth virial coefficient of free anyons, as a function of the statistics angle θ. It can be fitted by a four term Fourier series, in which two coefficients are fixed by the known perturbative results at the boson and fermion points.

Fourth- and fifth-order virial expansion of harmonically trapped fermions at unitarity
Physical Review Research, 2021 By generalizing our automated algebra approach from homogeneous space to harmonically trapped systems, we have calculated the fourth- and fifth-order virial coefficients of universal spin-1/2 fermions in the unitary limit, confined in an isotropic ...

Virial coefficients of multispecies anyons [PDF]
Physics Letters A, 2004 A path integral formalism for multispecies anyons is introduced, whereby partition functions are expressed in terms of generating functions of winding number probability distributions. In a certain approximation, the equation of state for exclusion statistics follows.

A new simplified virial equation of state for high temperature and high pressure gas
AIP Advances, 2022 In this paper, in order to accurately describe the high temperature and high pressure state of gas under detonation conditions, a new simplified form of the virial equation of state (EOS)—the Virial–Peng–Long (VPL) EOS—is proposed based on the ...

Toward an Automated-Algebra Framework for High Orders in the Virial Expansion of Quantum Matter
Condensed Matter, 2022 The virial expansion provides a non-perturbative view into the thermodynamics of quantum many-body systems in dilute regimes. While powerful, the expansion is challenging as calculating its coefficients at each order n requires analyzing (if not solving)

Equation of state for hard-sphere fluids offering accurate virial coefficients. [PDF]
Physical Chemistry, Chemical Physics - PCCP, 2016 The asymptotic expansion method is extended by using currently available accurate values for the first ten virial coefficients for hard sphere fluids. It is then used to yield an equation of state for hard sphere fluids, which accurately represents the ...
