Kinetic energy harvesting

open access: yes, 2008
This paper reviews kinetic energy harvesting as a potential localised power supply for wireless applications. Harvesting devices are typically implemented as resonant devices of which the power output depends upon the size of the inertial mass, the ...

Superconductivity by Kinetic Energy Saving? [PDF]

open access: yes, 2003
A brief introduction is given in the generic microscopic framework of superconductivity. The consequences for the temperature dependence of the kinetic energy, and the correlation energy are discussed for two cases: The BCS scenario and the non-Fermi ...

Can the Hartree–Fock kinetic energy exceed the exact kinetic energy?

open access: yesThe Journal of Chemical Physics, 2022
The Hartree–Fock (HF) approximation has been an important tool for quantum-chemical calculations since its earliest appearance in the late 1920s and remains the starting point of most single-reference methods in use today. Intuition suggests that the HF kinetic energy should not exceed the exact kinetic energy; but no proof of this conjecture exists ...

Kinetic energy density study of some representative semilocal kinetic energy functionals [PDF]

open access: yesThe Journal of Chemical Physics, 2007
There is a number of explicit kinetic energy density functionals for noninteracting electron systems that are obtained in terms of the electron density and its derivatives. These semilocal functionals have been widely used in the literature. In this work, we present a comparative study of the kinetic energy density of these semilocal functionals ...

Importance of the Doppler Effect to the Determination of the Deuteron Binding Energy [PDF]

open access: yes, 1999
The deuteron binding energy extracted from the reaction ${}^1H(n,\gamma){}^2H$ is reviewed with the exact relativistic formula, where the initial kinetic energy and the Doppler effect are taken into account.
