Query: Coherent Electron Dynamics in Thermal Lattice Vibrations   We develop a coherent state description of lattice vibrations to describe
their interactions with electrons. We construct the effective quasi-classical
field of the interaction, called the deformation potential, and study the
dynamics of an electron in this field nonperturbatively. The electron coherence
is preserved well beyond a single electron scattering event. Counting the
number of phonons in each vibrational mode becomes unnecessary. This is in
contrast to the conventional Fock state description of lattice vibrations where
an electron scattering event requires phonon creation or annihilation within
the first-order perturbation theory, and multiple scatterings are treated as an
incoherent and uncorrelated succession of the first-order scattering events
through Boltzmann transport theory. Here, we first show the consistency of the
coherent state picture with the conventional Fock state picture and then go
beyond by revealing new aspects that the conventional theory could not explain.
In particular, we observe electron coherence effects such as localization even
at high temperatures, and density of states exhibiting Lifshitz tails and
pseudogaps. Coherent electron-lattice vibration dynamics may shed light on the
unexplained phenomena in strange metals such as the violation of the
Mott-Ioffe-Regel limit, displaced Drude peak, existence of pseudogaps, and
universal linear temperature dependence of resistivity.
