AI Thread Summary
The standard simple harmonic oscillator (SHO) potential, expressed as V = mω²x²/2, describes systems that follow Hooke's Law, where the restoring force is proportional to displacement. This potential is commonly found in mechanical systems like springs and pendulums, where the angular frequency ω relates to the spring constant k and mass m through the equation ω = √(k/m). The discussion clarifies that the potential energy formula aligns with the SHO model, emphasizing the relationship between k and mω². Understanding this relationship helps in identifying physical situations governed by the SHO potential. The explanation highlights the importance of angular frequency in characterizing oscillatory motion.

Homework Statement


My QM book says that the standard SHO potential is m \omega^2 x^2/2. Can someone give me an example of a physical situation that is governed by this potential. It seems rather out of nowhere to me...

The Attempt at a Solution

 
Physics news on Phys.org
Any situation that is governed by Hookes Law: f=-kx, will have a potential V=kx^2/2
 
Yes but when is k = m \omega x? I guess \omega = g works, but
omega is usually an angle.
 
You are probably thinking of the oscillator potential energy using the formula:

V=1/2kx^2

Remember that Omega is the angular frequency of the oscillation. Also, remember that for an oscillator obeying Hooke's Law the angular frequency is:

\omega = \sqrt{k/m}

If you solve this for k, you should see where the m*omega^2 is coming from in the book's expression for the potential energy.
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
