Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures
Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Avances en Ciencias e IngenieríaWe estimate the dynamical mass of a Sloan Digital Sky Survey cluster using three techniques: (i) the classical virial theorem, (ii) a recent velocity–dispersion–mass scaling relation, and (iii) the caustic estimator based on the escape envelope in phase ...

Conformal Killing vector fields and a virial theorem
, 2014 The virial theorem is formulated both intrinsically and in local coordinates for a Lagrangian system of mechanical type on a Riemann manifold. An import case studied in this paper is that of an affine virial function associated to a vector field on the ...

Journal of Polymer Science, Volume 63, Issue 15, Page 3005-3022, 1 August 2025.ABSTRACT In this work, we systematically investigate the impact of counterion size on the behavior of star‐shaped strong polyelectrolytes in dilute aqueous solutions using Langevin simulations and a primitive model of electrolytes. Varying both the counterion diameter and the number of arms of the polyelectrolyte, we demonstrate that both ...

, 2010 We obtain two-sided bounds on kinetic and potential energies of a bound state of a quantum particle in the semiclassical limit, as the Planck constant $\hbar\ri 0$. Proofs of these results rely on the generalized virial theorem obtained in the paper as

Virial theorem and hypervirial theorem in a spherical geometry [PDF]
Journal of Physics A: Mathematical and Theoretical, 2011 The Virial Theorem in the one- and two-dimensional spherical geometry are presented, in both classical and quantum mechanics. Choosing a special class of Hypervirial operators, the quantum Hypervirial relations in the spherical spaces are obtained.

ChemistrySelect, Volume 10, Issue 30, August 8, 2025.Supramolecular contacts responsible for the mechanism of action of epothilone A chemotherapeutic drug in the taxane pocket of the β‐tubulin are addressed, combining quantum theory of atoms in molecules with density functional theory. We also derive the conformational shaping and the electronic eigenstates involved in photopharmacology experiments of ...

Virial theorem and gravitational equilibrium with a cosmological constant
Momento, 2001 Starting from the Newtonian limit of Einstein's equations in the presence of a positive cosmological constant, we obtain a new version of the virial theorem and a condition for gravitational equilibrium. Such a condition takes the form ρ > λρvac, where ρ

ThermoAtmospheric climate science lacks the capacity to integrate thermodynamics with the gravitational potential of air in a classical quantum theory. To what extent can we identify Carnot’s ideal heat engine cycle in reversible isothermal and isentropic ...

Jednadžbe stanja realnih plinova [PDF]
Kemija u Industriji, 2006 The properties of classical real gases, especially their deviations from ideal behaviour, are reviewed. After a brief overview of molecular interactions, the so-called traditional ('primitive') model is presented and shown to be applicable not only to ...
