Understanding "c.c." in Screened Potential Notation

AI Thread Summary
The term "c.c." in the context of the screened potential notation refers to the complex conjugate of the preceding term. In the expression Vsc(r,t)=Veiqre-iwteat+c.c., it indicates that the term should be added to its complex conjugate, which involves swapping the signs of q and w. This is a common practice in physics to ensure the potential is real. The discussion highlights the importance of recognizing complex conjugates in mathematical expressions. Understanding this notation is crucial for accurately interpreting condensed matter problems.

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!
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
