OK, that sounds like a physical reason, I can appreciate that. Thanks for your answer! Do you know if this is done analogously for other bosons?

Hey Everyone, I've a quick a question regarding the make-up of bosonic Green's functions, taking the free propagator for phonons as example. According to Mahan, 3rd ed. it is given by: D(q, \lambda, t-t')=-i\langle0|TA_{q}(t)A_{-q}(t')|0\rangle with A_{q}=a_{q}+a^{+}_{q} [ Eqs...

Huh, should've figured that out myself, makes sense. Thanks!

Hi, I encountered some unfamiliar notation in a condensed matter problem: Consider a screened potential of the form: Vsc(r,t)=Veiqre-iwteat+c.c. Could someone please explain to me the meaning of the term "c.c."? From the given context I can gather that it has something to do with...
