Bosonization/fermionization mechanisms

[DarkStar8]

What mechanisms are there for converting between bosons and fermions?

Bind Fermions together and you can get a Boson. Split a composite Boson and you might get Fermions. e.g. an electron and a proton make H-1, which is a Boson. A photon can create an electron/positron pair.

Well, there is supersymmetry which does exactly that, but we have no evidence that this is realised in nature.

 

In 1+1 dimensions there is a process called bosonization, where you take a system of interacting fermions and produce non-interacting bosons.
