Condensed matter physics

a phonon collision whose combined wavevector falls outside the first Brillouin zone, transferring momentum to the lattice and limiting thermal conductivity.

In condensed matter physics, Umklapp scattering refers to a phonon collision whose combined wavevector falls outside the first Brillouin zone, transferring momentum to the lattice and limiting thermal conductivity. This meaning comes from Peierls (1929) in Annalen der Physik.[1]
