###urms

Eq. (30) refers to ~/Dropbox/ntpl-paper/internal/turney_prb09_aLD.pdf:

The harmonic prediction works well for the perfect crystal, and also the amorphous phase at 1 K. However, for 5K and above the amorphous phase is more anharmonic. Even at T=1K, the amorphous phase has many meta-stable states, which contribute to larger fluctuations in the instantaneous values of <u^2>^{1/2}.

###book data

The meta-stability of the amorphous phase causes there to be negative correlation in the normal mode energies for the low frequency modes.
