Applicability of the cumulant expansion method for the calculation of transport properties in electron-phonon systems
Petar Mitrić, Veljko Janković, Darko Tanasković +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…

Charge transport limited by nonlocal electron-phonon interaction. II. Numerically exact quantum dynamics in the slow-phonon regime
Veljko Janković
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 Janković
Studying charge transport in models with nonlocal carrier--phonon interaction is difficult because it requires finite-temperature real-time correlation functions of mixed carrier--…
