SUMMARY

The discussion centers on the evaluation of a solution to the Gaussian wave packet problem in quantum mechanics. Parts (i) and (ii) of the solution are deemed professionally executed, while Part (iii) lacks rigor due to an unsubstantiated assertion regarding the time-dependent spreading of the probability density |Ψ(x,t)|². To enhance the professionalism of the argument, it is essential to perform the integral in equation (13), derive |Ψ(x,t)|², and demonstrate the time-dependent nature of the wave packet's width.

PREREQUISITES
  • Understanding of quantum mechanics principles, specifically wave packets.
  • Familiarity with probability density functions in quantum physics.
  • Knowledge of integral calculus as applied to quantum equations.
  • Experience with Gaussian functions and their properties.
NEXT STEPS
  • Perform the integral in equation (13) to derive |Ψ(x,t)|².
  • Research the concept of wave packet dispersion in quantum mechanics.
  • Study the mathematical properties of Gaussian functions in quantum contexts.
  • Learn how to justify assertions in quantum mechanics with rigorous proofs.
USEFUL FOR

Students and professionals in quantum mechanics, physicists analyzing wave packet behavior, and anyone looking to improve their mathematical rigor in quantum problem-solving.

Can some expert in Quantum say that my working is professional?
Kind wishes to you

Parts (i) and (ii) are rigorously explained so one may say that they are professionally done. Part (iii) is not "professional", mainly because you make an assertion without justifying it. You say that "the probability density ##~| \Psi(x,t)|^2~## spreads over time indicating that the wave packet disperses as time progresses." To make the argument stick, you need to do the integral in equation (13), find ##~|\Psi(x,t)|^2~##, identify the width and argue that it is time-dependent.
