Quantum acoustics unravels Planckian resistivity
Alhun Aydin, Joonas Keski-Rahkonen, Eric J. Heller
Strange metals exhibit universal linear-in-temperature resistivity described by a Planckian scattering rate, the origin of which remains elusive. By employing a novel approach insp…
Bragg scattering from a random potential
Donghwan Kim, Eric J. Heller
A potential for propagation of a wave in two dimensions is constructed from a random superposition of plane waves around all propagation angles. Surprisingly, despite the lack of p…
From Branched Flow to Superwires in Periodic Potentials
Alvar Daza, Eric J. Heller, Anton M. Graf +1
We report unexpected classical and quantum dynamics of a wave propagating in a periodic potential in high Brilloiun zones. Branched flow appears at wavelengths shorter than the typ…
Coherent charge carrier dynamics in the presence of thermal lattice vibrations
Donghwan Kim, Alhun Aydin, Alvar Daza +3
We develop the coherent state representation of lattice vibrations to describe their interactions with charge carriers. In direct analogy to quantum optics, the coherent state repr…
A formally exact master equation for open quantum systems
Li Yu, Eric J. Heller
We present a succinct and intuitive derivation of a formally exact master equation for general open quantum systems, without the use of an "inverse" map which was invoked in previo…
Branched Flow
Eric J Heller, Ragnar Fleischmann, Tobias Kramer
In many physical situations involving diverse length scales, waves or rays representing them travel through media characterized by spatially smooth, random, modest refactive index…
