Neutrino-nucleon scattering in supernova matter from the virial expansion
, 2017 We extend our virial approach to study the neutral-current neutrino response of nuclear matter at low densities. In the long-wavelength limit, the virial expansion makes model-independent predictions for neutrino-nucleon scattering rates and the density $

New Field-Theoretic Method for the Virial Expansion
Physical Review Letters, 2011 We develop a graphical method for computing the virial expansion coefficients for a nonrelativistic quantum field theory. As an example we compute the third virial coefficient b3 for unitary fermions, a nonperturbative system. By calculating several graphs and performing an extrapolation, we arrive at b3 =-0.2930, within 0.7% of a recent computation b3

EPJ Web of Conferences, 2013 A re-evaluation of the second virial coefficient of steam is presented in the paper. The work is a part of broader effort to develop a formulation of the properties of dry and metastable steam suitable for CFD computations.

Cluster expansion for the description of condensed state: crystalline cell approach
Condensed Matter Physics, 2018 A well-known cluster expansion, which leads to virial expansion for the free energy of low density systems, is modified in such a way that it becomes applicable to the description of condensed state of matter.

Hadron resonance gas with repulsive interactions and fluctuations of conserved charges
Physics Letters B, 2018 We discuss the role of repulsive baryon–baryon interactions in a hadron gas using relativistic virial expansion and repulsive mean field approaches. The fluctuations of the baryon number as well as strangeness-baryon correlations are calculated in the ...

Frontiers in Molecular Biosciences, 2019 The effects of macromolecular crowding on the thermodynamic properties of test proteins are determined by the latter's transfer free energies from a dilute solution to a crowded solution.

Nuclear Physics B, 2015 In the recently proposed two-parameter μ˜,q-deformed Bose gas model (Gavrilik and Mishchenko, 2013) [3], aimed to take effectively into account both compositeness of particles and their interaction, the μ˜,q-deformed virial expansion of the equation of ...

A solution to the combinatorial puzzle of Mayer’s virial expansion [PDF]
Annales de l’Institut Henri Poincaré D, Combinatorics, Physics and their Interactions, 2015 Mayer’s second theorem in the context of a classical gasmodel allows us to write the coefficients of the virial expansion of pressure in terms of weighted two-connected graphs. Labelle, Leroux and Ducharme studied the graph weights arising from the one-dimensional hardcore gas model and noticed that the sum of these weights over all two ...

Calculating and resumming the classical virial expansion using automated algebra
, 2023 Using schematic model potentials, we calculate exactly the virial coefficients of a classical gas up to sixth order and use them to assess the convergence properties of the virial expansion of basic thermodynamic quantities such as pressure, density, and
