Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have a question about basic Quantum Mechanics.

In free particle study of Quantum Mechanics, why do we use the Gaussian wave packet always? I know that the Fourier Transform of it is also a Gaussian wave packet, but I was thinking, is that what we have selected? or is that what nature has selected? I saw that in Schwabl and Cohen Quantum mechanics books.

I know also that the uncertainty principle is obtained very easily using the standard deviation through Gaussian distributions.

My friend has told me that if we used any other wave packet i.e. Lorentzian or anything else, we will obtain also the uncertainty principle, is that true?

Any answers or discussions about this?

Thanks
