A recursive enumeration of connected Feynman diagrams with an arbitrary number of external legs in the fermionic non-relativistic interacting gas
Erick Castro, Itzhak Roditi
In this work, we generalize a recursive enumerative formula for connected Feynman diagrams with two external legs. The Feynman diagrams are defined from a fermionic gas with a two-…

Entanglement between two spatially separated ultracold interacting Fermi gases
P. Alexander Bouvrie, Eloisa Cuestas, Itzhak Roditi +1
Multiparticle entangled states, essential ingredients for modern quantum technologies, are routinely generated in experiments of atomic Bose-Einstein condensates (BECs). However, t…

A combinatorial matrix approach for the generation of vacuum Feynman graphs multiplicities in theory
Erick Castro, Itzhak Roditi
From the standard procedure for constructing Feynman vacuum graphs in theory from the generating functional , we find a relation with sets of certain combinatorial matrice…
