Operator identity edit

Latest comment: 2 years ago1 comment1 person in discussion

Is there a source on the operator identity

e^{iLt}=e^{i(1-P)Lt}+\int _{0}^{t}dse^{iL(t-s)}PLe^{i(1-P)Ls}?

When comparing to Evans & Morriss, the second term lacks the imaginary unit. In Evans & Morriss, it reads (eq. (4.26))

e^{iLt}=e^{i(1-P)Lt}+\int _{0}^{t}dse^{iL(t-s)}iPLe^{i(1-P)Ls}?
