The negative sign pairing of energy and momentum operators are important characteristics of this paper. Then the Klein–Gordon equation and Dirac equation are introduced. The process of deriving relativistic energy–momentum relationship by undetermined coefficient method and establishing Dirac equation are ...

In particular, we are interested in modeling the collision of an electron with a phonon or/and photon in an active region with tunneling barriers, i.e., in a scenario where the energy and momentum operators do not commute. The path to achieve this goal requires first the answer to the fo...
Looking ahead to 2025, the momentum for clean energy may continue, pending new policy approaches from a new administration. The cleantech manufacturing, artificial intelligence, and carbon industries will likely continue to drive renewables deployment: On the demand side, many cleantech manufacturing, ...

It is demonstrated that a set of infinite number of conserved currents are constructed associated with particle emission vertex operators in string theory. Among which currents associated with zero mass particle vertices are useful in discussing the symmetry of the theory. The energy-momentum tensor op...
Changing the currentenergysystem requires the systematic training of professionals and skilled labor. 出自-2015年12月阅读原文 By far the biggest type of momentum that comes into play when it comes to changing ourenergysystems is economic momentum. ...
The symmetric energy-momentum tensor for the self-interacting fermion theory (ψψ)is expressed in terms of the collective mode within the Hartree approximation. The divergent part of the energy-momentum tensor for the fermion theory induces an effective energy-momentum tensor for the collective mode...
where the coordinate and momentum operators {x, p} refer to the Brownian particle and {qi, pi} are the coordinate and momentum operators of the i-th heat bath oscillator of mass mi and the eigenfrequency ωi. The parameter ci characterizes the coupling strength of the central system S with...
as well as slower than expected cash flows from new energy businesses. Against this backdrop, companies are recognizing that now is the time to maximize value creation in the traditional business, grow cash flows, and take advantage of the high returns. However, as this momentum grows, an old...
