Secular approximation

Is this the same as the secular approximation in open quantum systems? If so, it should be indicated somewhere. --MaoGo (talk) 16:16, 19 December 2018 (UTC)

No they are different. I have added this sentence and cited Mäkelä and Möttönen: "The rotating wave approximation is closely related to, but different from, the secular approximation." Jess_Riedel (talk) 11:43, 14 April 2022 (UTC)

Derivation

It seems like the Derivation is using

$H_{0}=\hbar \omega _{0}|{\text{e}}\rangle \langle {\text{e}}|-0|{\text{g}}\rangle \langle {\text{g}}|$

(e.g. setting energy zero to g) instead of the $H_{0}$ from above. Otherwise $U$ would take a different form. However, it claims to use what has been defined above. --Patrick
