SUMMARY

The discussion focuses on the conditions necessary for adiabaticity in a slowly varying harmonic oscillator. Specifically, it establishes that for a particle initially in the ground state to follow the potential adiabatically, the time rate of change of the frequency, represented as dω/dt, must be significantly less than the initial squared frequency, k₀/m₀. This relationship ensures that the system remains in its instantaneous eigenstate throughout the variation of the potential.

suppose that the potential of a harmonic oscilltor is changed slowly

i mean, the frequency of the harmonic oscilltor \omega is varying slowly

my question is, under what conditions, the particle initially in the ground state follow the potential adiabatically?

what conditions \omega(t) sholuld satisfy?

well, at the very least, it seems that the time rate of change of the frequency [itex]d\omega / d t[/itex] should be much less than then initial squared frequency. I.e.,
[tex] \frac{d\omega}{d t}<<k_0/m_0[/tex]
