Let [formula in source] be any finite set of momentum cells, with arbitrary dispersions [formula in source] , and define the graded tensor-product Hamiltonian [formula in source] . Then [formula in source] has a unique product ground state and The same number is the uniform lower edge of canonical one-fermion spectral support.
