Fermion operators
TensorKitTensors.FermionOperators.f_hopping — Function
f_hopping([elt::Type{<:Number}=ComplexF64], [symmetry::Type{<:Sector}=Trivial])
f_hop([elt::Type{<:Number}=ComplexF64], [symmetry::Type{<:Sector}=Trivial])Return the two-body operator that describes a particle that hops between the first and the second site.
TensorKitTensors.FermionOperators.f_min_f_min — Function
f_min_f_min([elt::Type{<:Number}=ComplexF64], [symmetry::Type{<:Sector}=Trivial])
f⁻f⁻([elt::Type{<:Number}=ComplexF64], [symmetry::Type{<:Sector}=Trivial])Return the two-body operator that annihilates a particle at the first and at the second site. It only has Trivial symmetry.
