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

if we have a potential of the form V(x) = a|x|, how would one go about estimating the ground state energy of the system using the heisenberg uncertainty principle.

I suppose the thing to do is to get an estimate of delta x, then get delta p via the heisenberg uncertainty principle and the E = delta p^2/2m but the particle could be anywhere on the real axis since the potential is finite on the interval (-inf,inf)!

any hint much appreciated
