Resonant phonons: Localization in a structurally ordered crystal
Albert Beardo, Paul Desmarchelier, Chia-Nien Tsai +3
Phonon localization is a phenomenon that influences numerous material properties in condensed matter physics. Anderson localization brings rise to localized atomic-scale phonon int…
