This lecture explores the simulation of excitons in disordered systems using effective mass path integral simulations, focusing on exciton dissociation and charge carrier trapping. It covers the modeling of excitons, effective mass theory, and the path integral formulation. The lecture delves into the electronic effects with effective mass theory, effective mass Hamiltonians, and the computation of the band structure. It also discusses exciton structure in solid KCl, perspectives from liquid state solvation, and delocalized quasiparticles in disordered systems. The presentation concludes with a study on defect screening in monolayer MoS2 and the impact of ionic liquids on defect screening and electron localization.
