Operator identity
Is there a source on the operator identity
 * $$ e^{iLt} = e^{i(1-P)Lt} + \int_{0}^{t} ds e^{iL(t-s)}PLe^{i(1-P)Ls}?$$

When comparing to Evans & Morriss, the second term lacks the imaginary unit. In Evans & Morriss, it reads (eq. (4.26))
 * $$ e^{iLt} = e^{i(1-P)Lt} + \int_{0}^{t} ds e^{iL(t-s)}iPLe^{i(1-P)Ls}?$$

 * That was indeed an error, equation has been fixed. Nerd2019 (talk) 12:49, 29 June 2024 (UTC)
