On Cluster Rotation in the Galactic Tidal Field

Open Astronomy, 2014
The dynamics of a rotating star cluster moving along a circular orbit in the axisymmetrical steady Galaxy is considered. The generalized tensor virial theorem allows to estimate its rotation speed.

Partitioning Entropy with Action Mechanics: Predicting Chemical Reaction Rates and Gaseous Equilibria of Reactions of Hydrogen from Molecular Properties

Entropy, 2021
Our intention is to provide easy methods for estimating entropy and chemical potentials for gas phase reactions. Clausius’ virial theorem set a basis for relating kinetic energy in a body of independent material particles to its potential energy ...

The Virial Theorem and Covalent Bonding [PDF]

, 2018
A long-held view of the origin of covalent binding is based on the notion that electrostatic forces determine the stability of a system of charged particles and that, therefore, potential energy changes drive the stabilization of molecules.

Dynamic virial theorem at nonequilibrium and applications

, 2023
We show that a variety of nonequilibrium dynamics of interacting many-body systems are universally characterized by an elegant relation, which we call the dynamic virial theorem.

Energy-momentum tensor in QCD: nucleon mass decomposition and mechanical equilibrium

Journal of High Energy Physics, 2021
We review and examine in detail recent developments regarding the question of the nucleon mass decomposition. We discuss in particular the virial theorem in quantum field theory and its implications for the nucleon mass decomposition and mechanical ...

Mesoscopic virial equation for nonequilibrium statistical mechanics

New Journal of Physics, 2016
We derive a class of mesoscopic virial equations governing energy partition between conjugate position and momentum variables of individual degrees of freedom.
