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…

Quantum-classical study of charge transport in organic semiconductors with multiple low-frequency vibrational modes
Darko TanaskoviÄ, Maksim Makrushin, Petar MitriÄ
Building on the recent success of a quantum-classical method for computing transport properties in the Holstein model with a single phonon mode [P. MitriÄ et al., Phys. Rev. B ${\…

Precursors to Anderson Localization in the Holstein Model: Quantum and Quantum-Classical Solutions
Petar MitriÄ, Vladimir DobrosavljeviÄ, Darko TanaskoviÄ
We calculate the frequency-dependent mobility of the Holstein polaron in one dimension near adiabatic limit using the method based on dynamical quantum tipicality, as well as the q…
