Algebra Level 5

$\large \dfrac{\left(\frac{a}{b}+\frac{b}{a}+1\right)\left(\frac{1}{a}-\frac{1}{b}\right)^2}{\frac{a^2}{b^2}+\frac{b^2}{a^2}-\left(\frac{a}{b}+\frac{b}{a}\right)}$

Given that $$a$$ and $$b$$ are distinct positive reals satisfying $$4a+b+\sqrt{ab}=1$$.

Find the minimum value of the expression above.
