According to this prescription, two cases need to be distinguished: the compact and the non-compact case. One of the possible rigorous ways to formulate a quantum theory with a modified uncertainty principle involving the position and momentum operators is the introduction of a modification in the...
These Heisenberg operators already contain the ini- tial position and momentum operator of the parti- cle. However, we have to combine them to access the momentum operator alone. Furthermore, this combina- tion has to describe an actual measurement, i.e., it must possess an operational ...
Given that angular momentum operators can be expressed in terms of position x and linear momentum operators pi (i = x,y,z), and that x and pi obey the following commutation relation: (2.180)[xm,pn]=jℏδmn;xm,xn=x,y,z, it can be shown that components of angular momentum satisfy...
Thus we are in the position to state the following: Theorem 4.1 A spacetime with Codazzi type of energy–momentum tensor T is a Yang Pure Space. 5. Spacetimes with quadratic Killing energy–momentum tensor In this section we consider a spacetime whose energy–momentum tensor T is quadratic ...

(ii) The physical interpretation of these quantities is difficult, and may not improve understanding of the process. (iii) Direct experimental evidence of the entanglement is often practically impossible, requiring the measurement of incompatible observables, such as momentum and position. One solution...
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 ...
