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…
Quantum Acoustics Demystifies the Strange Metals
Eric J. Heller, Alhun Aydin, Anton M. Graf +11
Phonons have long been thought to be incapable of explaining key phenomena in strange metals, including linear-in-\textit{T} Planckian resistivity from high to very low temperature…
Polaron catastrophe within quantum acoustics
Alhun Aydin, Joonas Keski-Rahkonen, Anton M. Graf +4
The quantum acoustic framework has recently emerged as a non-perturbative, coherent approach to electron-lattice interactions, uncovering rich physics often obscured by perturbativ…
Geometry-induced asymmetric level coupling
Alhun Aydin
Tailoring energy levels in quantum systems via Hamiltonian control parameters is essential for designing quantum thermodynamic devices and materials. However, conventional methods…
Shape-controlled Bose-Einstein Condensation
Cem Kurt, Altug Sisman, Alhun Aydin
Size-invariant shape transformation is a geometric technique that allows for a clear separation between quantum size and shape effects by modifying the shape of the confinement dom…
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…
