Eigenstate expectation values of the kinetic energy. Violet dots are results from an exact diagonalization calculation in a system with particles/sites. Panel (a) is for , panel (b) for . The grey dot is the result for the ground-state kinetic energy from the analytical doublon-holon calculation in the thermodynamic limit. Grey lines are expectation values for the first branch of single doublon-holon pair excitations. For increasing U the numerical results approach the analytical result as expected (differences arise from contributions with more than two-particles per site and finite size effects).
