Use of Special or General Relativity in QM?

[hagopbul]

why no one use the Special or General Relativity in QM (Quantum mechanics) ...

when QM studies particles that move in the speed of light (or near it)

in the same time the Special or General Relativity only be visible (its effect ) in such speeds

do not thing that QM perturbation is using Relativity theories

Really? How about the Dirac equation?

 

[hagopbul]

no it is not maybe in some way they use "some" of it but
you can not say that he use the Relativity theories
because ther is nothing about the mass change in it

Increasing mass is a fallacy, there is no such thing as "relativistic mass". However, Dirac's formulation is entirely consistent with the relativistic four-vector and can be applied to curved space-time. What more do you want?

 

[hagopbul]

OK i will reread about it do you know any book that is specialized in Dirac's theories only.

 

[Hootenanny]

I can recommend a text, but it is rather expensive: Relativistic Quantum Mechanics (Pure & Applied Physics) J.D. Bjorken, S.D. Drell. I'd recommend getting it from the library if you can.

Look up quantum field theory. It is a fully relativistic invariant formulation of quantum mechanics. It marries special relativity and quantum mechanics. As for general relativity, that's a whole different can of worms.

thanks we will talk later
