Artificial Harmonics

Hello there,

I'm looking for some help on how to notate artificial harmonics in both tabs and sheet music for guitar. I'm currently trying to transcribe the song Alpha Centauri by At the Drive In, and the song features one of the guitars playing the third fret harmonics throughout most of its verse. I was wondering then how I could do that, and also possibly also figure out how to get it to sound correct as well when played back (since I've heard that's kind of tricky to do with harmonics)

Here's the song in case anyone wants to hear it to see what I'm looking for:
