Exact calculation of spectral properties of a particle interacting with a one-dimensional Fermi gas in optical lattices
Abstract By using the exact Bethe wavefunctions of the one-dimensional Hubbard model with N spin-up fermions and one spin-down impurity, we derive an analytic expression of the impurity form factor, in the form of a determinant of a $$(N+1)$$ ( N + 1 ) by $$(N+1)$$ ( N + 1 ) matrix. This analytic ex...
