Simulations of positive streamers in air in different electric fields: steady motion of solitary streamer heads and the stability field
Hani Francisco, Jannis Teunissen, Behnaz Bagheri +1
We simulate and characterize positive streamers in ambient air in homogeneous background electric fields from 4.5 to 26 kV/cm in a 4 cm gap. They can accelerate or decelerate depen…
Simulation of positive streamers in CO and in air: the role of photoionization or other electron sources
Behnaz Bagheri, Jannis Teunissen, Ute Ebert
Positive streamer discharges have been studied and modelled extensively in air. Here we study positive streamers in CO with and without oxygen admixtures; they are relevant for…
The effect of the stochasticity of photoionization on 3D streamer simulations
B. Bagheri, J. Teunissen
Positive streamer discharges require a source of free electrons ahead of them for their growth. In air, these electrons are typically provided by photoionization. Here we investiga…
Getting excited: Challenges in quantum-classical studies of excitons in polymeric systems
Behnaz Bagheri, Björn Baumeier, Mikko Karttunen
A combination of classical molecular dynamics (MM/MD) and quantum chemical calculations based on the density functional theory (DFT) was performed to describe conformational proper…
Solvent effects on optical excitations of poly para phenylene ethynylene studied by QM/MM simulations based on Many-Body Green's Functions Theory
Behnaz Bagheri, Mikko Karttunen, Björn Baumeier
Electronic excitations in dilute solutions of poly para phenylene ethynylene (poly-PPE) are studied using a QM/MM approach combining many-body Green's functions theory within the $…
