Respected Sir,

I am Amit Choubey, MSc student of IIT Kharagpur, India. I am trying to solve Fermionic Hubbard Model using ALPS. But I am not able to understand how should I define the creation and annhiliation operator for fermions. Its because they follow an anticommutation relationship and the eigenvalues are dependent on the particular arrangement of the fermions. Please help me in this regard. An example describing this will be really nice of you.

Thanking You.

Sincerely, Amit Choubey

Just look at the models.xml file in ALPS for some examples
