Kinetic Energies in Quantum Solids

Physical Review Letters, 1985
We show that the recently measured kinetic energy of atoms in solid helium is substantially larger than expected for even a moderately anharmonic solid. The large kinetic energy is rather an explicit measure of the highly anharmonic nature of solid helium.

Kinetic Energy and the Stable Set

Qualitative Theory of Dynamical Systems, 2010
A classical result of Lagrange-Dirichlet states that in the theory of \(C^k\) mechanical systems, \(k\geq 2\), the strict minimum point for the potential energy \(\pi(q)\) is necessarily stable in the sense of Lyapunov. The first author and \textit{S. V.

Energy transfer and kinetics in mechanochemistry

Environmental Science and Pollution Research, 2017
Mechanochemistry (MC) exerts extraordinary degradation and decomposition effects on many chlorinated, brominated, and even fluorinated persistent organic pollutants (POPs). However, its application is still limited by inadequate study of its reaction kinetic aspects.

Kinetic energy of an electron gas

Physical Review B, 1985
We derive a simple expression for the correlation part of the kinetic energy of an inhomogeneous electron gas from density-functional theory. We show that in the local density approximation, this expression reduces to the virial theorem result ${t}_{\mathrm{xc}}=3{v}_{\mathrm{xc}}\ensuremath{-}4{\ensuremath{\epsilon}}_{\mathrm{xc}}$. We also derive the

Testing the kinetic energy functional: Kinetic energy density as a density functional

The Journal of Chemical Physics, 2003
A new method for defining an energy density for the noninteracting kinetic energy of density functional theory is given. The resulting energy density is a density functional determined completely by the kinetic energy functional itself. Although this method is not constructive, it allows for a direct comparison between exact and approximate functionals

The Kinetic Energy of Polyatomic Molecules

Physical Review, 1934
The Lagrangian and Hamiltonian expressions for the kinetic energy of a system of $N$ particles are obtained in such a form that the rotational, vibrational and coupling terms may be distinguished. The principal axes of inertia are used to define rotation.

Theorem of Kinetic Energy

2019
In this chapter, we will learn the theorem of kinetic energy. First, the concepts of work and kinetic energy are given. Then, the theorem of kinetic energy is introduced, and some examples are given to show the solving steps.
