What is the name of the transformation from one harmonic oscillator basis to another centered elsewhere?
If I have a harmonic oscillator basis centered at $x=2$, how do I rewrite it in terms of the harmonic oscillator basis centered at $x=0$? To be more specific:
If $|\Psi_n\rangle$ is the $n$th ...

Can motion be oscillatory but not periodic?
The equation of motion of a particle is $x = A \, \mathrm{cos}\left[(\alpha t)^2\right]$. What type of motion is it?
The answer to this question in my textbook was: "Oscillatory but not periodic&...

What is "equilibrium position" in simple harmonic motion?
In simple harmonic motion (SHM) is equilibrium position equal to the extreme position (i.e. where the external force and restoring force are equal), or where all kinetic energy of the body is ...

What is the difference between amplitude and phase angle for a pendulum?
I understand the definition in terms a plain trigonometric function, such as $A\cos(\omega t+\phi)$. The amplitude is half of the distance between peak and bottom, and the phase angle* is how the ...

Oscillator what's the steady state?
I'm wondering what's the steady state for an oscillator.
Is it a system without driving force so without external force to disturb the system?
If a system oscillates without driving force can we say ...

More appropriate statement for the SHM
I know that the energy of SHM is given by
$$E=\frac 12 kA^2$$
So which of these is more appropriate to say?
Energy is increases because amplitude is increased.
Amplitude is increased because ...
