Electron correlation in semiconductors and insulators via symbolic regression
Nick Pant, Viet-Anh Ha, Donghwan Kim +1
Predicting quasiparticle energies in materials requires expensive numerical evaluations of the electron self-energy. This limits calculations to ordered systems with small unit cel…
Low-energy tail of the spectral density for a particle interacting with a quantum phonon bath
Donghwan Kim, Bertrand I. Halperin
We describe two approximation methods designed to capture the leading behavior of the low-energy tail of the momentum-dependent spectral density and the tunnelin…
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…
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…
Schroedinger Correspondence Applied to Crystals
Eric Heller, Donghwan Kim
In 1926, E. Schroedinger published a paper solving his new time dependent wave equation for a displaced ground state in a harmonic oscillator (now called a coherent state). He show…
