Renormalization of excitonic properties by polar phonons

  title={Renormalization of excitonic properties by polar phonons},
  author={Yoo Kyung Park and David T. Limmer},
We employ quasiparticle path integral molecular dynamics to study how the excitonic properties of model semiconductors are altered by electron-phonon coupling. We describe ways within a path integral representation of the system to evaluate the renormalized mass, binding energy, and radiative recombination rate of excitons in the presence of a fluctuating lattice. To illustrate this approach, we consider Fr¨ohlich-type electron-phonon interactions and employ an imaginary time influence functional…

Ab initiotheory of polarons: Formalism and applications
We develop a theoretical and computational framework to study polarons in semiconductors and insulators from first principles. Our approach provides the formation energy, excitation energy, and
Nonlocal Screening Dictates the Radiative Lifetimes of Excitations in Lead Halide Perovskites.
We use path integral molecular dynamics simulations and theory to elucidate the interactions between charge carriers, as mediated by a lead halide perovskite lattice. We find that the charge-lattice

A variational technique is developed to investigate the low-lying energy levels of a conduction electron in a polar crystal. Because of the strong interaction between the electron and the
Phonon Screening of Excitons in Semiconductors: Halide Perovskites and Beyond.
It is demonstrated that the magnitude of the phonon screening correction in isotropic materials can be reliably predicted using four material specific parameters: the reduced effective mass, static and optical dielectric constants, and frequency of the most strongly coupled longitudinal-optical phonon mode.
Effective Hamiltonians and bindings energies of Wannier excitons in polar semiconductors
The interaction of Wannier excitons with an LO-phonon field is investigated in detail. We derive effective local Hamiltonians which may be used to calculate the whole exciton spectrum in a

Effective mass path integral simulations of quasiparticles in condensed phases.
This work introduces an approach for studying quasiparticles in condensed phases by combining effective mass theory with the path integral treatment of quantum particles, and incorporates the generally anisotropic electronic band structure of materials into path integral simulation schemes to enable modeling of quasIParticles in quantum confinement.

We present a recently developed approach to calculate electron-hole excitations and the optical spectra of condensed matter from first principles. The key concept is to describe the excitations of
Calculating polaron mobility in halide perovskites
Lead halide perovskite semiconductors are soft, polar, materials. The strong driving force for polaron formation (the dielectric electron-phonon coupling) is balanced by the light band
