comment Why must phonon-phonon interaction be anharmonic?
@CountIblis I can't quite understand why if I defined phonons as harmonic linear combinations, then the interactions woudn't happen. I'd greatly appreciate some clues. Thanks :)

@CountIblis Thanks for the answer. Could you elaborate a little bit about defining interactions as linear combinations? What does that imply? Also if you could elaborate your second sentence a little bit. What happens when I diagonalize the matrix? Isn't that ok?

comment Will adding heat to a material increase or decrease entropy?
What about "smart materials" with "memory"? If you put them in hot water they restore the previous shape. So if I distort them at room temperature, I create chaos, but then putting them in hot water, increases their temperature and they become more ordered (take shape I programmed the material to be)?
