Three-site fermionic operator in systems of spinless fermions
Hello! While working wth systems of spinless fermions, I ran into a problem with construction of the Hamiltonian terms which are three-site. They look like $\psi^{\dagger} U^{\dagger} \psi$. $U$-operator represents local gauge field and has mathematically the same form as $\psi$-operator. I create a...
