High-precision Quantum Monte-Carlo study of charge transport in a lattice model of molecular organic semiconductors
Pavel Buividovich, Johann Ostmeyer, Alessandro Troisi
We use first-principle Quantum Monte-Carlo (QMC) simulations and numerical exact diagonalization to analyze the low-frequency charge carrier mobility within a simple tight-binding…
