Discussion Overview

The discussion centers around the invariance of the Schrödinger equation under Galilean transformations, exploring the conditions under which such invariance may hold and the challenges encountered in proving it.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant attempts to prove the Galilean invariance of the Schrödinger equation but encounters an extra term related to velocity, suggesting a potential mistake in their approach.
  • Another participant asserts that the Schrödinger equation is not invariant with respect to Galilean transformations.
  • A different participant suggests modifying the wavefunction by multiplying it with a space-time dependent phase factor as a possible approach to achieve invariance.
  • A link to external material is provided, referencing a source that may contain relevant information on the Galilean transformation of the Schrödinger equation.

Areas of Agreement / Disagreement

Participants express differing views on the invariance of the Schrödinger equation under Galilean transformations, with no consensus reached on the matter.

Contextual Notes

The discussion highlights the complexities involved in proving invariance, including the introduction of additional terms and the need for modifications to the wavefunction, but does not resolve these issues.

im trying to prove the galileo invariance of s.e. But i get stuck with an extra term prop.to v*d/dx
in fact i get invariance only for scaling x' equ. ax and t' equ. at.
Where does the mistake hide ?

Can't do it, it isn't invariant with respect to Galilean transformations.
 
Try to change the wavefunction as well: multiply it by a space-time dependent phase factor.
