In several books I have seen the statement that due to Heisenbergs principle no particle can be localized into a region of phase space smaller than ##(2 \pi \hbar)^3##. However, Heisenbergs uncertainty principle states that ##dx dp \geq \hbar/2## -- so a direct translation of this should imply that the minimal volume must be ##(\hbar/2)^3## and not ##(2 \pi \hbar)^3##. So, what am I missing here?(adsbygoogle = window.adsbygoogle || []).push({});
