SUMMARY

The discussion centers on the Galileo invariance of the Schrödinger equation (S.E.), specifically addressing the challenges encountered when attempting to prove this invariance. The user reports encountering an additional term proportional to v*d/dx, indicating that invariance is achieved only under specific transformations of space and time (x' = ax and t' = at). The user suggests modifying the wavefunction by multiplying it with a space-time dependent phase factor to resolve the issue. Reference to a specific book is provided for further reading on the topic.

PREREQUISITES
  • Understanding of the Schrödinger equation in quantum mechanics
  • Familiarity with Galilean transformations
  • Knowledge of wavefunction modifications in quantum mechanics
  • Basic concepts of invariance in physical equations
NEXT STEPS
  • Study the implications of Galilean invariance on the Schrödinger equation
  • Research the role of phase factors in quantum mechanics
  • Explore the mathematical derivation of the Schrödinger equation under Galilean transformations
  • Examine the content on page 5 of the referenced book for detailed insights
USEFUL FOR

Physicists, quantum mechanics students, and researchers interested in the foundational principles of quantum theory and the behavior of wavefunctions under transformations.

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.
