SUMMARY

The discussion centers on the quantum mechanics (QM) problem of a classical particle moving under a potential V(x) represented by the Hamiltonian H = p² + V(x). It explores the relationship between this scenario and a particle constrained to move on a surface, particularly when V(x) = 0 and when considering the Christoffel symbols, Γ^i_{jk}. The conversation highlights the distinction between quantum and classical descriptions, emphasizing that in standard QM, there are no classical paths or positions, only probabilities can be calculated. The implications of applying classical theories, such as those proposed by Einstein, to quantum scenarios are critically examined.

PREREQUISITES
  • Understanding of Quantum Mechanics principles

USEFUL FOR

Physicists, students of quantum mechanics, and researchers interested in the intersection of quantum theory and classical mechanics, particularly those exploring particle dynamics under constraints.

My question is if the QM problem of a classical particle under a potential V(x) so [tex]H=p^{2} +V(x)[/tex]

Is the same of this problem of a particle constrained to move under a surface with the additional condition [tex]V(x)=0[/tex]

Or a particle moving on a surface with [tex]\Gamma ^{i}_{jk}[/tex]

So the potential is obtained from the 'Christoffel-Symbols'.

This problem is similar to the classic one by Einstein,.. where for 'weak field' you obtain Newton equation for the Potential..then my problem is if you can apply the same to QM

Hi tpm. You seem to jumping between theories too freely. The description in quantum terms of the bound particle is very different from the classical or GR scenario. They are not related in the way you imply. Have you studied QM ? There are no classical 'paths' or 'positions' in standard QM, and only probablities can be calculated.
