Hhokhani replied to the thread Graduate Time evolution of a detected particle.As far as I know, from elementary quantum mechanics, while we are measuring the position, the position would be one of the eigenstate of...

Hhokhani replied to the thread Graduate Time evolution of a detected particle.Sorry I don't understand. Could you please tell where I am wrong! We have the expansion of the wave function as ##\delta(x-x_0)=1/2\pi...

Like.
No, the particle's speed is extremely uncertain. It could be almost light speed or it could be zero. And it could be moving in any... -
Hhokhani replied to the thread Graduate Time evolution of a detected particle.Thanks, how does the infinite momentum uncertainty predict light speed for the particle whereas it seems that the expectation value of...

HSuppose that we detect a quantum particle at the position ##x_0##. Then, we would like to know about its position at a next time. Does...
