SUMMARY

The term "c.c." in the context of the screened potential notation Vsc(r,t)=Veiqre-iwteat+c.c. refers to the complex conjugate of the preceding term. This notation indicates that the expression includes both the original term and its complex conjugate, which is essential for ensuring the physicality of the potential in quantum mechanics. Understanding this notation is crucial for interpreting the behavior of screened potentials in condensed matter physics.

PREREQUISITES

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 swapping the sign of q and w, but I'd be grateful for a more precise definition.

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