Thanks for the link, I derive it the same way. You're right. If they use 2π/L then they must take the entire k-space into consideration, because they didn't differ between +/-. Where as if you take the π/L if did already differ between positiv and negative solutions and you only take the...

Hi guys, I have a very particular question on the derivation of DOS. For a particle in an infinite box k=π/L. However, when deriving the density of states, all textbooks use k=2π/L Now you could argue that they account for spin degeneracy, but its not that! Because in the textbooks that...
