Probability \(\pmb{Pijk}\) for each state \(\pmb{|ijk\rangle}\) in the Hubbard model with three fermionic modes. The physical parameters used are hopping \(h=1\), together with (a\(U=1\) and number of Trotter steps \(n=4\), (b\(U=1\) and \(n=10\), (c\(U=0.5\) and \(n=4\), and (d\(U=0.5\) and \(n=10\). The initial state is in all cases \((|011\rangle+ |101\rangle)/\sqrt{2}\). Dashed lines refer to numerical solutions without Trotter approximation, and solid lines to numerical solutions with Trotter approximation.
