Importance of nonlinear long-range electron-phonon interaction for the carrier mobility of anharmonic halide perovskites
Matthew Houtput, Ingvar Zappacosta, William Wenborn +4
The interaction between the electrons and the lattice vibrations in a solid is responsible for various important effects, such as formation of polarons, temperature dependent bandg…
First-principles theory of nonlinear long-range electron-phonon interaction
Matthew Houtput, Luigi Ranalli, Carla Verdi +4
Describing electron-phonon interactions in a solid requires knowledge of the electron-phonon matrix elements in the Hamiltonian. State-of-the-art first-principles calculations for…
First-principles theory of nonlinear long-range electron-phonon interaction
Matthew Houtput, Luigi Ranalli, Carla Verdi +4
Electron-phonon interactions in solids are crucial for understanding many interesting phenomena, such as conventional superconductivity, temperature-dependent band-gap renormalizat…
Analytic method for quadratic polarons in nonparabolic bands
Serghei N. Klimin, Jacques Tempere, Matthew Houtput +4
Including the effect of lattice anharmonicity on electron-phonon interactions has recently garnered attention due to its role as a necessary and significant component in explaining…
Low-Lying Collective Excitations of Superconductors and Charged Superfluids
S. N. Klimin, J. Tempere, H. Kurkjian
We investigate theoretically the momentum-dependent frequency and damping of low-lying collective excitations of superconductors and charged superfluids in the BCS-BEC crossover re…
Polaron with Quadratic Electron-phonon Interaction
Stefano Ragni, Thomas Hahn, Zhongjin Zhang +9
We present the first numerically exact study of a polaron with quadratic coupling to the oscillator displacement, using two alternative methodological developments. Our results cov…
