The effects of added salt on the second virial coefficients of the complete proteome of E. coli [PDF]

, 2002
Bacteria typically have a few thousand different proteins. The number of proteins with a given charge is a roughly Gaussian function of charge - centred near zero, and with a width around ten (in units of the charge on the proton).

Optical Kerr and Cotton-Mouton effects in atomic gases: a quantum-statistical study

, 2013
Theory of the birefringence of the refractive index in atomic diamagnetic dilute gases in the presence of static electric (optical Kerr effect) and magnetic (Cotton-Mouton effect) fields is formulated.

Virial expansion coefficients in the harmonic approximation

, 2012
The virial expansion method is applied within a harmonic approximation to an interacting N-body system of identical fermions. We compute the canonical partition functions for two and three particles to get the two lowest orders in the expansion.

Two hard spheres in a spherical pore: Exact analytic results in two and three dimensions

, 2008
The partition function and the one- and two-body distribution functions are evaluated for two hard spheres with different sizes constrained into a spherical pore. The equivalent problem for hard disks is addressed too.

On a Self-Consistency Thermodynamical Criterion for Equations of the State of Gases in Relativistic Frames

Entropy, 2013
More than three decades ago, Tykodi and Hummel proposed a procedure to investigate the self-consistency thermodynamical criterion for equations of the state of gases.

Virial expansion with Feynman diagrams

, 2011
We present a field theoretic method for the calculation of the second and third virial coefficients b2 and b3 of 2-species fermions interacting via a contact interaction. The method is mostly analytic. We find a closed expression for b3 in terms of the 2

A polymer gas on a random surface [PDF]

, 1998
Using the observation that configurations of N polymers with hard core interactions on a closed random surface correspond to random surfaces with N boundary components we calculate the free energy of a gas of polymers interacting with fully quantized two-

Virial coefficients and osmotic pressure in polymer solutions in good-solvent conditions [PDF]

, 2006
We determine the second, third, and fourth virial coefficients appearing in the density expansion of the osmotic pressure of a monodisperse polymer solution in good-solvent conditions.

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 ...
