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 ...

The most important examples are: energy eigenvalues and eigenvectors of the harmonic oscillator and the hydrogen atom, eigenvalues and eigenvectors of position, momentum, and angular-momentum operators. So, why it is not allowed in some cases while in other cases it is ok? Is there a rule ...
magnetic dipole transitions of excited atoms within or near a dielectric media. They compared the vacuum quantization scheme with that of the system including the dielectric and proved that the coefficients connecting the creation and annihilation operators of both methods can be interpreted as ...
