Difference in transmission one vs two delta functions
I'm looking at a potential described by two deltafunctions, V(x)=V0d(xq) + V0d(x+q). There is a particle coming in towards the barrier from the left with energy E. I have found the transmission coefficient for the doubledeltapotential. And I can see that for some values of E,V0 and q the transmitted flux is greater than for a single deltapotential. Why is that?
