In this paper,we study the diagrammatic categorification of the fermion algebra.We construct a graphical category corresponding to the one-dimensional(1D) fermion algebra,and we investigate the properties of this category.The categorical analogues of the Fock states are some kind of 1-morphisms in our category,and the dimension of the vector space of 2-morphisms is exactly the inner product of the corresponding Fock states.All the results in our categorical framework coincide exactly with those in normal quantum mechanics.
In this paper, we study the diagrammatic categorification of the fermion algebra. We construct a graphical category corresponding to the one-dimensional (1D) fermion algebra, and we investigate the properties of this category. The categorical analogues of the Fock states are some kind of 1-morphisms in our category, and the dimension of the vector space of 2-morphisms is exactly the inner product of the corresponding Fock states. All the results in our categorical framework coincide exnetlv with those in normal quantum mechanics.
