Use of Special or General Relativity in QM?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between Special and General Relativity and Quantum Mechanics (QM). Participants explore whether and how relativistic concepts are integrated into QM, particularly in the context of particles moving at or near the speed of light.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants question why Special or General Relativity is not commonly used in QM, suggesting that QM deals with particles at relativistic speeds where relativity should be relevant.
  • Others point out that the Dirac equation incorporates relativistic principles, implying that there is a connection between relativity and QM.
  • One participant argues that while some aspects of relativity may be used, the concept of mass change is not addressed in QM, leading to the assertion that relativity theories are not fundamentally utilized.
  • A later reply challenges the notion of "relativistic mass" and emphasizes that Dirac's formulation aligns with relativistic four-vectors and can be applied to curved spacetime.
  • Another participant introduces quantum field theory as a framework that integrates special relativity with quantum mechanics, suggesting it addresses the concerns raised about the relationship between the two fields.

Areas of Agreement / Disagreement

Participants express differing views on the extent to which relativity is incorporated into quantum mechanics. There is no consensus on whether QM fundamentally utilizes relativity theories, and the discussion remains unresolved regarding the implications of relativistic concepts in QM.

Contextual Notes

Some claims about the integration of relativity into QM depend on specific interpretations of mass and the applicability of certain equations, which remain open to debate. The discussion also touches on the distinction between special and general relativity in the context of quantum mechanics.

Who May Find This Useful

This discussion may be of interest to students and researchers in physics, particularly those exploring the intersections of quantum mechanics and relativity, as well as those studying advanced topics like quantum field theory and relativistic quantum mechanics.

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?
 
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?

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