Time-Dependent Schrodinger Eq: Integrating Time?

Click For Summary
SUMMARY

The discussion centers on the integration of time into the time-independent Schrödinger equation within quantum mechanics (QM). The participant questions whether incorporating time is as straightforward as in classical physics, suggesting that the Hamiltonian can provide momentum and velocity, which could be used to introduce time-dependence. They acknowledge their limited experience with the time-dependent Schrödinger equation and recommend further study of classical mechanics, specifically referencing Goldstein's "Classical Mechanics" as a foundational text. The conversation emphasizes the complexity of time's role in QM compared to classical mechanics.

PREREQUISITES
  • Understanding of the time-independent Schrödinger equation
  • Familiarity with Hamiltonian mechanics
  • Basic knowledge of classical mechanics principles
  • Mathematical proficiency in integration techniques
NEXT STEPS
  • Study the time-dependent Schrödinger equation in detail
  • Review Hamiltonian mechanics and its applications in quantum mechanics
  • Read Goldstein's "Classical Mechanics" for foundational concepts
  • Explore peer-reviewed papers on the integration of time in quantum mechanics
USEFUL FOR

Students and researchers in physics, particularly those focusing on quantum mechanics and classical mechanics, will benefit from this discussion. It is also valuable for anyone seeking to deepen their understanding of the mathematical foundations of time-dependent equations in physics.

My own question, carried to a new thread as not to derail another:

This brings another question to mind, regarding whether that information (time) is already implicitly present [in the time-independent Schroedinger equation]. In modern physics is it as easy to integrate time into an equation as it is with classical physics?

My line of thought being that if you have the Hamiltonian, you have momentum, which contains velocity, which can be separated and integrated as dx/dt to introduce a time-dependence.

I've seen the formula for the time-dependent equation, but I haven't followed the mathematical development of it. I've only really worked with the one-dimensional, time-independent Schrödinger equation... and the math is still shaky for me.

Volumes have been written on this subject -- google for it, and focus on the papers from peer reviewed journals -- there's quite a bit of crack all over on this topic. You might want to learn classical mechanics a little further -- Goldstein, Classical Mechanics is the classic (no pun intended) reference. Understanding the role of time in classical mechanics is a prerequisite before you move on to the much trickier situation in QM. Suffice to say that momentum and velocity have almost exactly nothing to do with each other.
