# AutoMPO for mixture of fermionic and bosonic basis

I would like to simulate a Fermionic chain interacts with a single (soft) Bosonic site. I guess I can define a SiteSet to encode the degree of freedom and the local operators. My question is, if I use this SiteSet in AutoMPO, will AutoMPO generate the correct MPO, or is there any problem I should notice?

One thing I can imagine is that I may need to define the Jordan-Wigner operator "F" as identity operator for the Bosonic site. Is it right?

Any comment on the mixing basis will be appreciated!
