is there any book discussing goldstone mode?
i am not very familiar with field theory. Could anyone suggest some books accessible to a non-field-theory theorist?
i guess the acoustic phonon is a goldstone mode but the optical phonon is not.
Since a goldstone mode is associated with a broken symmetry and for a N-dim solid, N translational symmetries are broken, there are N and only N acoustic modes.
