Quantum Harmonic Oscillator

Click For Summary
SUMMARY

The discussion centers on the quantum harmonic oscillator, specifically addressing a scenario where the stiffness of the spring is reduced by a factor of f2, resulting in a new natural frequency of f2ω. The main question posed is about calculating the probability of finding the oscillator in an energy state of 1.5(hbar)f2ω after this change. Participants emphasize the need for a clear attempt at solving the problem to facilitate effective assistance.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly the quantum harmonic oscillator.

A harmonic oscillator with frequency ω is in its ground state when the stiffness of the spring is instantaneously reduced by a factor f2<1, so its natural frequency becomes f2ω. What is the probability that the oscillator is subsequently found to have energy 1.5(hbar)f2ω? Thanks
