Finite potential well transmission coefficient
.
does that mean 2a*sqrt(2m(E+V_0))/hbar = npi only apply for bound states? And E>0 scattering states will always "pass" the well?

Finite potential well transmission coefficient

Thats cool! If I rearrange the equation 2a*sqrt(2m(E+V_0))/hbar = npi (This is when there is 100% transmission), I get...

A potential barrier is like this image right? Whereas a potential well is the opposite. Ok so a particle with E>0 may be reflected...

Supremum of a set, relations and order

Ok so you’re supposing s is the supremum of S, which when squared should be a number that is extremely close to 2, but not exactly since...
