不幸的是，之前投AJP的文章 Fermi's golden rule: its derivation and breakdown by an ideal model，又被拒（审稿77天）。
再次验证一个教训：to be pedagogical is too difficult！
Dear Prof. Jiang Min Zhang,
Attached you will find copies of the reviewers' reports on your manuscript "Fermi's golden rule: its derivation and breakdown by an ideal model," our manuscript #28709.
As you can see, the reviews are quite mixed: one in favor of publication, one against, and one "ambivalent". Faced with this lack of consensus, I have read the manuscript myself and I regret to conclude that although it may be suitable for publication elsewhere, it is too narrowly technical and cumbersome to be useful to most AJP readers.
AJP receives many submissions, almost all of which have some value. However, we can only accept a limited number of manuscripts and thus manuscripts must receive enthusiastic support from reviewers for further consideration. I am writing to inform you, therefore, that we will not pursue publication of this manuscript.Thank you for your interest in the American Journal of Physics.
