Applicability of the cumulant expansion method for the calculation of transport properties in electron-phonon systems
Petar MitriÄ, Veljko JankoviÄ, Darko TanaskoviÄ +1
We assess the accuracy of the cumulant expansion (CE) method, combined with the independent-particle approximation (IPA), for calculating charge mobility in electron-phonon systems…
Numerically "exact" charge transport dynamics in a dissipative electron-phonon model rationalizing the success of the transient localization scenario
Veljko JankoviÄ
Optical conductivity in molecular semiconductors is suppressed in the terahertz region, featuring the displaced Drude peak that reflects carriers' transient localization (TL) by sl…
Charge transport limited by nonlocal electron-phonon interaction. II. Numerically exact quantum dynamics in the slow-phonon regime
Veljko JankoviÄ
Transport of charge carriers in mechanically soft semiconductors is mainly limited by their interaction with slow intermolecular phonons. Carrier motion exhibits a crossover from s…
Charge transport limited by nonlocal electron-phonon interaction. I. Hierarchical equations of motion approach
Veljko JankoviÄ
Studying charge transport in models with nonlocal carrier--phonon interaction is difficult because it requires finite-temperature real-time correlation functions of mixed carrier--…
