2-particle irreducible (2PI) feynman diagrams
Let me preface this by saying that I'm not too code-savvy, which is probably why I need to ask this here. As a first step, I want to find a way to generate 2-particle irreducible (2PI) Feynman ...

Is there a program or a website able to perform all Wick contractions for a given expression?
Imagine I have an expression of the type:
$$\langle \phi_{x_1} \phi_{x_1} \phi_{x_2} \phi_{x_2} \phi_{z_1} \phi_{z_1} A_{z_1} \phi_{z_2} \phi_{z_2} A_{z_2} \phi_{z_3} \phi_{z_3} A_{z_3} \phi_{z_4} \...

Software for calculating Feynman Diagrams
Is there a software (open source preferred) where I would input something like "Ingoing: a fermion $(p1, s1)$ and a photon $(p2, s2)$. Output: A fermion $(k1, r1)$ and a photon $(k2, r2)$" and I would ...
