Fully Analytical Evaluation of Second Virial Coefficient with Stockmayer Potential and Its Applications

, 2020
In this study, fully analytical treatment for evaluating the second virial coefficient with Stockmayer potential is presented. This approach is based on the binomial expansion theorems and basic integrals for the analytical representation of the second ...

Equilibrium States of Galactic Atmospheres. I. The Flip Side of Mass Loading

The Astrophysical Journal
This paper presents a new framework for understanding the relationship between a galaxy and its circumgalactic medium (CGM). It focuses on how imbalances between heating and cooling cause either expansion or contraction of the CGM.

The equation of state of isotropic fluids of hard convex bodies from a high-level virial expansion

, 2005
We have calculated virial coefficients up to seventh order for the isotropic phases of a variety of fluids composed of hard aspherical particles. The models studied were hard spheroids, hard spherocylinders, and truncated hard spheres, and results are ...

Isotropic and nematic phases of the hard spheroid fluid: A virial approach

, 2012
We use a high level virial expansion to investigate the properties of the isotropic and nematic phases of the hard spheroid fluid. We use the Monte Carlo techniques described previously to calculate the virial coefficients up to seventh order and we ...

Dynamic response and failure analysis of nanoporous Al plate under compression and stretching

AIP Advances
It is widely known that porous structure design is an important way to reduce the weight of matrix materials. However, there is still a lack of systematic understanding of how factors such as the shape, size, and concentration of pores affect the dynamic

CO Observations of the SMC-N66 H ii Region with ALMA: Properties of Clumps Along Filamentary Molecular Clouds and Possible Expansion Motion

The Astrophysical Journal
The star-forming region N66, as a host of the majority of OB stars in the Small Magellanic Cloud, provides a unique opportunity to enhance our understanding of the triggers of high-mass star formation. We investigate the properties of the molecular cloud

Constraints on Dark Matter Self-interactions from Weak Lensing of Galaxies from the Dark Energy Survey around Clusters from the Atacama Cosmology Telescope Survey

The Astrophysical Journal
Self-interactions of dark matter particles impact the distribution of dark matter in halos. The exact nature of the self-interactions can lead to either expansion or collapse of the core within the halo lifetime, leaving distinctive signatures in the ...

Second Order Virial Expansion for an Atomic Gas in Harmonic Waveguides

, 2015
International audienceWe study the virial expansion for a quantum gas in a 1D or a 2D atomic waveguide. We use a two-channel Hamiltonian which takes into account the coherent coupling between atoms and molecules near a possible Feshbach resonance.

Impulsive Mixing of Stellar Populations in Dwarf Spheroidal Galaxies

The Astrophysical Journal
We study the response of mono-energetic stellar populations with initially isotropic kinematics to impulsive and adiabatic changes to an underlying dark matter potential.

Virial expansion for weakly correlated polymer solutions

, 1981
A recent paper by Eichinger solved for the radial distribution function g(r) and the osmotic pressure for polymer solutions, starting from a linearized hypernetted chain (HNC) equation with the assumption that the force between pairs of molecules is ...
