Theory¶
Feynman Path Integrals¶
Uses Feynman Path Integral formulation... we can write the mean of an operator A as
\[\langle \hat{A} \rangle = \frac{ \int_{-\infty}^\infty
dx' \int_{x'}^{x'} \mathcal{D} x(t) e^{- \frac{S_E [x]}{\hbar}}
A(x(t_1))}{\int_{-\infty}^{\infty}dx' \int_{x'}^{x'} \mathcal{D} x(t)
e^{- \frac{S_E [x]}{\hbar}}}\]
Sampling¶
Bisection.... We are good ppl
