Elastic, Quasielastic, and Superelastic Electron Scattering from Thermal Lattice Distortions in Perfect Crystals
Eric J. Heller, Anton M. Graf, Yubo Zhang +2
In standard treatments of electron transport, momentum relaxation in a perfect, defect-free crystal is linked with phonon creation or annihilation. In this work, we reconsider this…

Adiabaticity Crossover: From Anderson Localization to Planckian Diffusion
Tiange Xiang, Yubo Zhang, Joonas Keski-Rahkonen +2
We investigate electron transport in one dimension from the quantum-acoustic perspective, where the coherent-state representation of lattice vibrations results in a time-dependent…

Planckian Diffusion: The Ghost of Anderson Localization
Yubo Zhang, Anton M. Graf, Alhun Aydin +2
We find that Anderson localization ceases to exist when a random medium begins to move, but another type of fundamental quantum effect, Planckian diffusion , rises t…
