Introduction to Quantum Mechanic
... It is not surprising to find that quantum mechanics does not predict the position of an electron exactly. Rather, it provides only a probability as to where the electron will be found. We shall illustrate the probability aspect in terms of the system of an electron confined to motion along a line o ...

In special relativity the space-time symmetry is enlarged by Lorentz transformations which mix x and t, transforming them as the components of a fourvector. The generators of translation in spaceand time are the total momentum P and the tota ...

Localization and the Semiclassical Limit in Quantum Field Theories
... The question now is whether classical relativistic particles and their dynamical evolution can be also recovered from the quantized bosonic fields in the limit ~ → 0. An important problem here is to identify appropriate localized states and position operators in the context of relativistic quantum ...

However, here adjointness allows for either sign, which is interpreted as a mass density which is positiv ...
