Hi everyone(adsbygoogle = window.adsbygoogle || []).push({});

When a momentum operator followed by a position operator acts on a wave vector what does it give? (or the other wave around, changing the order)

Is this the collapse of a wave function? And if so, can we solve this to predict the answer or not?

I tried but got stuck in the math,

It is difficult to show the math here.. but the procedure that i used is:

assume a state that is a superposition of both position eigen state and momentum eigen state. (I hope that can form a state, i mean it should)

Now when this state is acted upon by the position operator: well it should pick out the position state (collapse)

but actually the momentum state is fourier transform of X vector, so X° can operate on that too...

and then P° can act on it...

Does this seem fine? I was expecting X° will pick out X state and then P° will have to act on that.... like collapse..

I am guessing my idea of a collapse of wave function is flawed.

(I studied QM using the Schrodinger's wave function approach and these kets n operators confuse me..)

I will be happy if someone could help me with these ideas and point out exactly what is wrong.

Thanks
